About 2 1/2 yrs ago, I started hanging at C4Tech, trying to figure out how to cure a miss. It turned out to be a bad injector.
After removing the plenum and the injector rail, I started thinking about an intake upgrade. (Everybody berades the TPI as a 305 intake, don't you know!) Plus, I started asking some of you guys about emissions equipment and other stuff. (Central Coaster and Bogus had their opinions about that!) Because I wanted to keep my car running clean enough to pass emissions, I kinda stayed focused on the TPI stuff. It was the "Ten Times the Torque" article that helped me decide that a SR might be best. But, some forum feedback steered me away from that route. After finally deciding on a heavily modified, siamesed SLP with big base (to create a SR-like power curve for street performance), I got to wondering about my 20-yr-old valve springs. (Someone mentioned how their 89's were low -- due to age). Even with only 55k miles, that got me thinking about refreshing my heads for the next 10yrs. Seemed like the smart thing to do considering my mileage and how I LOVE this car! Of course that led to the need for headers. Then, I decided my oil seals weren't the best. And, what about that original clutch hydraulic system? What about the clutch for that matter? Next thing I know, I building a WHOLE DAMN MOTOR, replacing the CHS, and putting in a new clutch/DMF combo. That's after learning how to polish aluminum, port intakes, and a whole lot of other stuff. So....Wanna see what happens after you pull apart an intake to replace a bad injector? In my case, you build this 383 stroker! :lol:        I included this last one, taken with my camera phone under shop lights.  Moral of this story....Sell your car when the injectors start acting up! Thanks for looking! :rofl: gp PS...If you want, I'll post a pic or two of how I siamesed/MEGA-ported my intake. |

When it's installed depends on how much time I spend detailing engine compartment, installing CHS, permantly mounting intake, etc... Hopefully within the next 2-3 wks though.
I'm curious about the pics. When I come back to this thread, my pics show up small -- approx 2"x2" in size. In photobucket, they're about 6 times bigger. Right after I posted, 1 of the pics was large and the others were small. Now,,,they're all small. And...they don't enlarge when I click on them. In fact, they say image deleted! What do you guys see? Any idea about the problem? EDIT: When I click edit, they show up BIG! WEIRD!!! |

Like I told you before, Gregg, motor looks awesome. It makes me itchy to get mine back.
As far as the pics, when you use photobucket you have to insert the pictures as the "html" version. They will scale down to a thumbnail for the thread, but if you click them they will reopen. Otherwise, if you use firefox, you can right click on the picture and hit "view image (picture?)" and it will display in a large size but by itself. Matthew |

I'm going with 24Bosch SVO's. Probably w/o an AFPR...at least to start.

Sharp looking engine! That should be on the cover of a magazine. A well put together TPI setup is hard to beat for appearance. The SLP runners really give it a muscular look. Of course I'm heavily biased.
Myron Cottrell says in his Tpis book that "the stock 350 injector is capable of flowing enough fuel for over 450 hp." Attach file:  P1010007.JPG (119.58 KB) |

How do you plan on setting up your PCV or breathers with those valve covers?
Nice work. I'm assuming those are the repops with perimeter bolt adapters on the heads? |

OK, so a guy has a setup running 24s with good ETs. Not to knock it, but it doesn't say that running 26 through 32s would have been better or worse for him with a tune. There was no comparison between injectors. What could he have run with a bigger size? I'm thinking I want to run a minimum of 26s and maybe bigger based on the calculators I've seen. But I don't know yet. Matthew PS - look at this link, too. Similar info, but more. http://forums.corvetteforum.com/c4-te ... hip-burn-for-a-383-a.html |

Look back at the top-view pic. There are PVC cutouts. They are on the inside (intake side) of the valve covers -- above the "C" in "Corvette". These valve covers are HEAVY duty cast alum. You could T-bone someone running out of a bar and not bend them! LOL Because of the extra-heavy-duty casting, they don't flex upon install. They're SO rigid, the centerbolt versions only come with the outside 2 holes drilled! AFR heads come drilled for both centerbolt and perimeter bolt valve covers. (No adapters required to use either type of valve covers.) |

Thanks for your advice to change to HTML vs IMG for this website. I did and pics are large size now. As far as the injector question, you do know 24SVOs are the Ford units that flow almost 26lbs in our rails, right? Also, with a TPI motor, peak will definitely be BELOW 6k rpms. My torque will be higher than HP because of the TPI config. I chose the 24's for this TPI setup because they come is a silver metal case that can be polished. If I swap the intake to an HSR, then I might go to 30lb injectors. More likely, I'd up pressure to 50psi. Either way, I'll put a guage on my rail to make sure where I'm at. (Plus data scans and a couple of dyno runs.) As far as the debate of whether a 26lb vs 32lb injector is better: Alvin, Accel, and FIC have all stated (at least implied) that the use of a smaller injector should lead to better results. For one thing, a larger injector can have a harder time with idle and low rpm atomization. By contrast, the smaller injector won't. Even at higher rpms, I believe a smaller injector (driven at a higher pressure) can acheive better results than the bigger one. But, that's my interpretation of several statements I've read -- including a couple in the thread you just linked. |

Well...they're not cheap. I got them thru the manufacturer found in the following link: http://www.yourcovers.com/valve_covers_11026.php Notice plain cast are $220 and polished are $375. Notice also, that drilling the breather holes is another $80! With shipping, you're around $500 for them to do all the work.  To avoid half the cost, I ordered them plain. Then I drilled and expanded the holes to 1" via carbide burr, bought generic PVC grommets from O'Reilly's, sanded and polished myself.  One good thing about these covers though...They're sturdy as heck and they're between standard/high covers (meaning rockers should clear fine. Plus,,,they have a built in baffle cast inside. |

yes a smaller injector will help on idle as the smaller injector will be open longer then a larger injector to deliver the same amount of fuel. That said, on my old 89 Miniram motor I was running 30# Ford Motorsport injectors. my motor was a 350, miniram, 52mm TB, CNC L98 heads, ZZ9 cam. I had the injector constant set for 36# so I could adjust my VE tables better (was running a 1991 ECM and dash) and to be honest it idled/drove quite well. I was running stock pressure too, not sure you really need to change the pressure, just tune the ECM. Now I know the 89 runs MAF, but if you want to get into tuning, check out the DynamicEFI system, uses a stock computer and has quite alot of features, not only that but it will still run the OEM dash info.. |

Wanna see some pics now that the motor is installed?
I've only driven it about 100 miles. I'm getting closer to unleashing what's inside but I can already tell it's a wild torque monster!!! With barely over half throttle, it'll shoot from 20mph to 60mph in about 2 seconds. (2nd gear). 3rd gear pulls WAY harder than 2nd used to. 4th even has some serious guts. I can even cruise at 45mph in 6th! With the stock motor, I could never have gotten it to hold it's speed below 55-60mph. FWIW: It has a sinister low-frequency rumble thru SpinMaster muffler....  Click on Video....(before installing mufflers) |

http://www.yourcovers.com/ Notice they do have centerbolt versions of the covers. I bought the plain cast, polished, and cut out the PCV/breather ports. The manufacturer also offers that option too. Note: These are not OEM covers. They are taller and do a better job of allowing the installation of higher ratio rockers. |

Whoa Momma! That's the way a Vette engine is supposed to look. Was it a problem getting the wire bundles out of the way so you can run the pvc and breather hoses along the top of the valve covers?

Nope. I wrapped the OEM injector harnesses with silver thermo tape to help them blend into the background. The PVC's will just barely clear what's wrapped (to go in the side-mounted valve cover holes.) But, they will go in. No other change(s) made except the elimination of EGR and AIR - related equipement. |
