I have been thinking about building a "new" engine for my 90 since it has 135K on it and it has some oil blow-by.
I found a guy locally that has a 383 short block for sale pretty cheap. It has a spun bearing and bad piston. He doesn't know the cam specs but I figured that I'd end up having to change that anyway. I know that I need to make sure that it is a roller cam. My mind got to turning on this. I obviously am not a ASE tech so I have no idea how to tell if it truly is a 383. Is there a way to visually identify it as such? How badly would I be choking it if I bought it, had it gone over and fixed then put my stock 113 aluminum heads and tpi on it? Any idea a ballpark on how much a machine shop might charge to get the block back in shape? The only numbers that he can find on it are 00062. It is supposed to be a GM replacement block with dipstick holes on both sides. The budget for this is really small so it might be more of a pipe dream than anything. |

The difference between the 350 and the 383 is the rotating assembly.
Do you know which bearing is spun? Rod or main? If a rod bearing spun, the rod and crank is going to need work / replaced. If a main bearing spun it'll need to be line bored and have over sized main bearings installed. If you have a limited budget, I would pass on that project. The machine shop labor is going to out cost what your parts will amount to, but both together will be more than I think you're ready for. It costs just about as much to rebuild a 383 as it does a 350 assuming you are replacing the rotating assembly anyway. If I were you, and wanted a 383, I would find a good donor block that's already been machined, and buy your rotating stock. Build your own stroker. |

I don't necessarily want or need a 383. He posted the block on TGO for $375 but I think he's getting to the point where I could go get it for a bit less. I was trying to google that # on the block but didn't find anything.

The other thing is the block. Those blocks with dip sticks on both sides are 2pc rear seals while your 90 will have a 1pc real seal.
You will have to change the flywheel to use it and the oil pan is different and may not fit in a Corvette. Be aware those blocks were mainly service replacements for trucks so the starter pad may only be drilled for a 168tooth FW - so you MIGHT have to buy a new starter as well. As durango said the difference in a 383 and 350 is the rotating assy mainly the crankshaft and pistons. If it spun a main, the block will have to be line bored/honed. It cost $150.00 to line hone a block in my dads shop. If it spun a rod, the crank will have to be turned and the rod will have to be replaced or rebuilt. Sometimes they can not be saved. Turn the crank cost $120.00 and to rebuild one rod cost about $25.00. With all the differences and known problems.... then what about the unkown problems like why did it blow up the first time?? It's probally not cost effectlve to fix and use this engine. Tell me what your budget is and I'll be glad to try and see what I can find for you. Will |

Well, since I just had my heads gone through at a reputable machine shop what I was really hoping to do is get a short block to put them on. I don't need anything wild, stock would be fine with me. I have brand new lifters too. So basically I need a block with the rotating assembly right?
Hoping to keep it under a grand. |

For less than a grand you're looking for a project engine that someone else finished and is selling for fast cash.
If you buy a project you'll spend more than that every time. |

Jeff, I am going to strongly advise you against going the 383 route.
If you have the desire to pull your motor and have it rebuilt, that's awesome! But I think you want a stockish, reliable, long lasting motor for your car. If I were you I would pull it and take it to a reputable shop near your house to have the machine work done. Have the block cleaned up, have the cylinders honed .30 over (it'll be a 355), new bearings, etc. Get the crank turned if necessary. Buy some hypereutectic pistons and get them assembled on your stock rods that can be polished. Reuse everything you can. Get the heads rebuilt, maybe a little bowl blending/port job while you're at it. A 383 is not "pennies more" like everyone always says. BS. True that the cost *difference* is not as much if you are buying a whole new rotating assembly to begin with, but you don't need that. Figure over $4,000 for a 383 by the time it's all said and done. I'm guessing you can do a stock rebuild with a nice new cam for under $1500. Matthew |

Matthew,
Thank you for being honest. Everything from lifters up is new/rebuilt. I saw a set of 30 over pistons on TGO for $100 with rings. I can drive it as is for now and was thinking more of getting it through the summer as is and doing the engine in the fall/winter. I think my wife would be more acceptable to the car being drivable until the weekend when I pull the motor to swap the bottom end. Which I think is doable with 2 people right? |

Mine is far from a show car. It's supposed to be my daily but new issues keep popping up preventing me from using it as intended.
Looking through the Summit site they have re-ring kits including pistons/gaskets/oil pump for around $350. |

I agree. You could re-use your block, crank and rods and build a good 355 for little cost. Here is a little break down of what I would recommend you buy and what it would cost you.
Parts: I'd recommend the Speed Pro H345CP hyper piston which are $120.00 from Comp Products. http://www.competitionproducts.com/Sp ... B-350/productinfo/H345CP/ Some Hastings 2M139 Moly Rings $36.00 http://www.competitionproducts.com/Ha ... Bore/productinfo/2M13930/ King CR807 Rod and MB557 Main brgs. $16.00 and $20.00 http://www.competitionproducts.com/Ki ... 010/productinfo/CR807010/ http://www.competitionproducts.com/Ki ... 010/productinfo/MB557010/ Dura Bond CH-8 Cam brgs. $15.00 http://www.competitionproducts.com/Du ... Chev-SB/productinfo/CH-8/ Melling M55 oil pump. $20.00 http://www.competitionproducts.com/Me ... -265-400/productinfo/M55/ Pioneer P101B Brass Freeze plug kit. $14.00 http://www.competitionproducts.com/Fr ... -Brass/productinfo/P101B/ Gasket Set. I don't have my books infront of me and my internet search skills are failing me on a complete gasket kit for the L98. I think they are about $200.00 Labor: Hot tank block $50.00 Bore and hone your block $150.00 Turn Crankshaft 10/10 $120.00 Press/Install pistons $85.00 Install Cam Brgs $75.00 Install Freeze plugs $25.00 Total Parts $441.00 Total Labor $505.00 You can buy the pistons cheaper and save a few bucks if you want to shop around. Like these Speed Pro H345ACP on Ebay. $92.00 is a good deal.... http://cgi.ebay.com/ebaymotors/Hyper- ... top-SBC-NEW-/300545136677 If your crank dosen't need to be turned and the gaskets can be pieced together cheaper your actually well under budget.

Jeff, if I did it over, I'd find a block to build (out of a third gen is perfect) and do it in the garage, then swap it out all at the same time. Two guys makes it go faster, I did almost my entire swap alone

This could be a very good way for you to go.
The L31 block is the same as the l98. Passenger side dip stick, 1pc rear seal and machined for factory roller cam. The factory assembled one is $1189.95 and that is a decent price. It has a 13cc dish piston and that is going to hurt your compression over flat tops. With the stock 58cc heads and using a thin Victor Reniz .026 composite head gasket you compression ratio would only be 9.89.... Using the Felpro 1094 shim (.015) you can manage 10.14. Now I'm estimating the pistons are .020 in the hole (about right for GM factory) and if the are less (say .015 in the hole) your compression ratio will be a tick higher, up to 10.26. No matter which way you go it's still a higher compression ratio than your stock 90's (9.5). The L31 has good points like the 4 bolt main's, but the PM rods aren't anything to brag on (not bad either) and the crank is a standard cast iron GM unit - just like what you already have. You will still need to buy gaskets and an oil pump. With careful selection on your head gaskets (I'd use the Fel Pro 1094) and a small cam or stock cam and 1.6 rockers you could have a good engine for the money. Will |

If I went that way I would still have to get
- Oil pump - timing set - cam (Would probably go LT4 hotcam) - oil pan (gorilla stripped my drain plug hole) - gaskets ( I should be a major stock holder in Fel-pro by now) sound about right? |

Sounds about right. In that case you'll need to re-use your intake manifold, rocker covers, cyl heads, rockers, pushrods, cam retainer/thrust plate, lifters, lifter guides/dogbones, lifter guide retainer/spyder, oil pump drive shaft, oil pump pick up screen, timing cover, harmonic balancer and flex plate/flywheel. The Hot Cam would run good on a TPI with 10.1-10.26SCR and a little head work. Of course you'll need new LT4 valve springs for the Hot Cam and you'll want to put the new valve seals that come in the gasket kit on there as well. You would probally want 1.6 rockers and to plot the rocker geometry/pushrod length but you could probally get by with re-using the stock stuff. Will |

That sounds pretty good depending on what is done, what parts are installed, and the level of assembly. Do you have a specific list? My advice is get everything in writing.

That's a fact! That is one of the hardest things to do. My builder gave me an estimate with everything that was going to be done and parts... but it was not itemized. It was just a bottom line figure without letting me know how much I was spending on what. Then that number ballooned as the build went on. I know better but didn't prevent this from happening. |

Here is what I asked him to price.
"I just bought new lifters for the engine thatÂ’s in the car. So I wonÂ’t need you to supply those. I am also going to buy the cam from a Corvette vendor so thatÂ’s covered. So basically all that I would be looking for is a roller cam block with all new freeze plugs, bearings and rotating assembly. Passenger side dipstick." We had already talked about it being for a TPI car and he said that he would use flat top pistons. He said that if I wanted an aftermarket cam it would be an additional $320. |

You can save the oil pan by drilling the drain plug oversize, and using a larger bolt. $100 or more back into the budget if you save it. Factory timing chain sets work fine too. Just buy a $10 set of degree bushings to be sure it phases in properly. That could put another $40 or $50 back into the budget compared to a double roller chain set. |

I'm not sure why he is cheaper than the GM replacement other than the fact that I doubt he's using a brand new block.
I might do that with the oil pan. As far as the timing set goes, rock auto has the stock replacement set for under $40 which isn't too bad. I haven't had time to even look at the Vette let alone take the time to sit down and figure out what I want to do about this. Classes are over this week so maybe next week I'll get my stuff together. |

You got to figure his cost of the parts is pretty low as I'm sure he buys from a huge parts distributor like EPW or Carolina.... You can buy "good enough" parts really cheap from them.
Cast Badger flat top pistons are only like $60.00 a set, Clemex or ACL or Engine Tech brgs $15 a set, cast ring set, ect.... He can charge whatever he wants for labor/machine work. I can remember when a friend of mine who owned a general engine rebuild/machine shop was trying to compete with the cut rates and he told me he could actually turn a small profit building and selling a stock rebuild 350 SBC for like $950.00 just using what was ever parts were on closeout or sale at EPW. It's possible but I don't think your getting the best stuff. Of course it's all in how good of parts you need and it may be fine. If you can get an itemized break down of the parts he will use, me or PeteK can tell you for sure. Will |

Well, the verdict is in. So here's the dilema...
I can get the GM shortblock for $1350 to my door, I know for sure what's in it and it's a 4 bolt main. I can get the guy 2 hours from here to build a short block with questionable parts/quality of work for $900 + $250 core fee. |

Why don't you want to use the original block and build it up if you are going to go for option 2 above?
I can see the time factor being important to you in that you want to be driving not working on the car which option one would give you. Wouldn't it be better to keep the original engine block in it. Maybe that doesn't matter on a C4. I'm just thinking out loud........ |

When I looked up the specs for the 90 Corvette there is some disagreement on the factory compression ratio.
When you did the heads on your car did it have flat top 4 valve relif pistons or a dished top 4 valve relif piston? Will |

One reason is because I have to rent/borrow a engine hoist and I'd rather have the "new engine" ready to drop back in after I get the old one out. As far as numbers matching.. I'm not concerned about that since I've been slowly changing out the interior to black and a few other odds and ends. Plus everyday that it sits in the garage I am putting more miles on my leased VW. |

I can't remember how many valve reliefs they had but they were flat tops. I just talked to a guy in Raleigh that takes wrecked Vettes, parts them out and then rebuilds the engines. He is a former dirt track racer that used to build race engines to help pay for his hobby. He has a 91 engine that he is working on right now. It's out getting hot tanked. Then it is going to his machinist to get bored .30 over then he is going to get it back install hypereutic pistons and all the other goodies. I told him that my heads have been recently gone through and have the LT4 springs on them and that I have new lifters and so on. He said that if I bring him my heads / lifters and return my block to him when I get it out we would be in the $1000 area. He said that he checks all the bearing clearances / ring clearances and so on. I also mentioned that I wanted to do the LT4 hotcam and he said no problem. So he would also knock the price of the cam off the total. Now doing some reading maybe the LT4 cam isn't the way to go. |

OK stock flat tops means 10.25 stock. With the L31 GM shortblock your going to lose a .25 point of compression.... With the hotcam and your other bolt ons it will still make good power (way more than stock) but I don't know if I would want to spend $$$$ to have a new engine with lower than stock compression. Do you get any input on what parts the guy in Raleigh uses? |

He said the brand on the pistons and bearings and it was one that I had heard of but of course I can not think of it for the life of me.
Will, Maybe I should hire your new persona as my mediator. This is not going to be the L31 it is going to be a machined 91 Corvette stock crank so I shouldn't loose any compression right? I also scored a set of mega ported SLP runners with matched plenum the other day. |

All 350 Chevy's use a 3.48" stroke crank and 5.7" rods. Compression largely depends on what pistons he uses, what headgaskets and the deck height of the block (how far that piston is in the hole).
Be aware that all flat top pistons are not created equally. Some have the compression height shortened, thus lowering you compression ratio - because the piston will be further in the hole. Make sure of what parts he is using and what machine work is is being done before you agree to deal with him. It sounds like it could be a really good deal for you if the guy is really on the up and up. Don't be afraid to ask the guy again. It's your $$$ and tell him thats this is a big descision for you and your just trying to evaluate all your options. I know there is alot of stuff to keep track of but I just want you to get the best motor for your $$$. As always I'll be glad to look over whatever he tells you and give you my opinion. Will |

I emailed him and asked him to go over what products he is going to use and what work is being done to the block... here's his response.
Jeff, I will be using Mahle Hyper flat top pistons standard comp. ratio, Perfect Circle moly piston rings, Durabond cam bearings, brass freeze plugs, Clevite 77 rod and main bearings, standard Melling oil pump or High volume high pressure Melling pump for additional charge, Melling standard timing chain set or double roller set at additional charge and all gaskets and seals are Felpro. I only use good brand name parts it is not worth it to me to use the cheaper stuff, you get what you pay for. The block has been completely stripped and hot tanked it will then be bored to the piston specs, deck will be left at standard 9.025 deck so compression ratio will remain the same as stock. Are there any other questions I should be asking? I don't think that I am going to do the high volume oil pump, I've read nothing good about them. Not sure about the timing set though. Any suggestions? Thanks, Jeff |

There is nothing wrong with the parts he is using. I actually like what I'm seeing and hearing.
The oil pump comes down to the brg clearance and oil weight you intend to run... 90% of the time a HV pump is not needed. Lets say 5% of the time the engine bilder set the brg clearance up specifically to run one. The other 5% of the time some clown just used one because he didn't know any better. Since he is leaving the deck uncut I would suggest you wait until the short block is assembled and ask him to measure how far the piston is in the hole. If they are -.020-.025 I would suggest you spend a little extra money ($40) on the Fel Pro 1094 headgaskets and bring them with you for him to assemble the engine with when he puts your cyl heads on. If you can get me the piston to deck measurement and the Valve relief CC's I can tell what your Static Compression Ratio will be. Since your using the hot cam I'll be able to calculate your Dynamic Compression Ratio as well. I would recommend the double roller timing set. Specifically this one: http://www.summitracing.com/parts/CLO-9-1145/ Will |

I found that some of the oval track warehouses are selling the Mahle flat top pistons.... But they weren't listing any specs except for bore size. I called JR Motorsports (who I have an account with) and found that they have 4cc Valve Relifs.
Provided they end up .025 (they should) in the hole and you use the Fel Pro 1094 gasket. Quench .040 SCR 11.32 DCR 8.74 If you use the Victor Reinz 5746 Quench .051 SCR 10.98 DCR 8.49 If you use the Fel Pro 101 or a similar .040 compressed stock gasket. Quench .064 SCR 10.57 DCR 8.19 It has the potential to be a sweet running engine. Will |

Wow Will! I really appreciate you checking into all of that. I think I used the 1094's when I put the heads on last time too.
Is there a reasonable priced street cam that I can order from Summit that you would reccomend over the hot cam? |

Thinking back, I used the 1010 head gaskets last time with a quench of .39

Compressed distance of the gasket is .039. With your piston to deck being -.025 (in the hole), you add both of them together to determine piston to head (quench), which would be .064. As for the cam. I think the GM LT4 hot cam is a good choice. Will |

Popped the driver side head off tonight.
#1 exhaust valve already has some flaky carbon build up on it after the heads have only been run maybe 100 miles. [IMG]http://i149.photobucket.com/albums/s46/kresge1975/1305506865.jpg[/IMG] Close up on #1 chamber [IMG]http://i149.photobucket.com/albums/s46/kresge1975/1305506863.jpg[/IMG] |

I talked to the guy last night. The block is at the machine shop. I'm taking my heads and the other stuff that we are re-using to him on Monday night. Engine should be ready for Memorial Day weekend.
I ordered the cam from Scoggin-Dickey and they sent it Fedex home delivery to my billing address with signature required not to the shipping address I provided so I had to sign the door tag for them to leave it. I hope it's still there tonight when I get home. and of course Jim on the other forum has a sweet deal on a 383 now that I've committed to the local guy. Always my luck. |
