I'm talking the sweet spot. 90% of the time your engine operates at what RPM? I hit new poll but I'm an idiot, maybe one of the mods can fix it. 3000 and less 3500 and less 4000 and less 4500 and less 5000 and less Over 5000

Senior Guru San Diego, CA 9454 Posts Member since: 2007/10/28 0:00	Depends on what heads/cam package I'm running. Right now I spin my motor to 4200rpm and shift. But you can bet your ass if my hp peaks at 6000rpm, I'm gonna spin my motor to 6200. 90% of the time my engine operates at 1500 rpm and 1/4 throttle and makes 20 hp. Perhaps I should optimize my motor for that. So then what heads do you suggest jsup? These circa 1985 cast iron anvils with 150cfm are flowing way too much for my application.

Nope How often do you race? 5-6 times a year or less now, but 40 times or so years ago Is it more race car or street car? Without a doubt, street car. Most would have zero clue I ever raced the car, based on it's sound and appearance.

If the power/torque curve is the same for any of the heads you like up to the max RPM you ever want to run, it will make absolutely no difference. In my example I have roller lifters, which most of us do, so the safe physical limitation is 6500. The practical limitation is probably an occasional 6000. Is that a good answer?

It does everything better on the street than a Corvette, except break the speed limit. We put hp in these cars because we can, whether or not we use it. It's no different than the waxer driving his F250 with 36" super swampers on the freeway next to you. Even at the track, most people have no good reason for modding their car, as they never learned to drive it right to begin with in stock form. Anyhow have you made any plans on heading to the track? I would suggest a shift light to make sure you're using everything you paid for.

Now if youre a waxer who likes to show off a sheet, brag then thats something else. Strange but guys do it. Know a few with 600 rwhp dyno sheets that have never been down a track in their life and never will get the thrill of putting it all down through all the gears. I dont get that but whatever.. Would you stick a supermodel in the closet and not wear her out like a cheap tool to "save it for the next guy"? I think not.

The lack of revs is what I really disliked about my L98, which was essentially dead at 4500. I am amazed how strong the LS7 is all the way up to 7000. That is screaming for a 427!

It has the stock roller lifters in it still. I think flashing to 6500 then shifting to the next gear, like while accelerating, it is fine at that or maybe even higher if the springs are good to keep valve float from happening. Now if I were to sustain those rpms for any amount of time I feel sure it wouldn't last long.

I don't bust on people for misspellings or bad english but geesh, I know you can do a little better. Do you have the crossfire intake still? If so, porting it can help alot. Headers and dual exhaust can free it up. I personally wouldn't do the roller rockers till after the intake porting and exhaust work. I'd think you could rev it to 6000 occasionally without harm, if that is what you meant by "how much rs". A higher stall converter can really wake it up too, and if it has 2.59 gears swap them out for 3.07's or 3.54's.

I hate to be rude, but, wow, I thought my L-98 at 245 HP was anemic. Just get a new motor or leave it stone stock.

Senior Guru 258 Posts Member since: 2008/1/25 0:00	Yea, Brian, that looks just like an L83! With enough boost, a Briggs and Stratton will run 12's. From the above link: "All the Crossfire Corvettes tested with horsepower ranging between 118 to 146, were totally stock. A few needed a good tune-up with 118. Most averaged between 122 to 128. A few with free flow exhaust, under drive pulleys, 160 degree thermostat & fan switch, K&N air filter, new or rebuilt distributor with 9 mm wires and AC platinum plugs, a stage 2 performance chip and Mobil 1, 5W30 oil produced a range of 133 to 146. One Crossfire which had been extrusion honed was also tested. It produced 166 hp with the same modifications as the above 146 hp Corvettes. It basically showed a 20 hp increase over a well tuned engine. The X-Ram with the addition of a 85 Tuned Port Fuel Pump was also tested on each one of these cars and produced and average of 171 to 217 horsepower. That was an increase of 53 to 71 horsepower at the rear wheels." So, I guess if you want to spend some money, you can help it, but geeze, 118 HP stock? I remember dyno'ing a Firebird with a 305 and a 2 barrel carb and it was rated 205 HP and made 89 RWHP. Here is a brand new GM Performance Parts 350ci / 290hp engine for $1950: http://www.sdpc2000.com/catalog/crate ... ci290hpEconomyEngine.aspx FInd a used Mini ram or similar and have 2x the L83 HP and probably better gas milage.

Senior Guru Tyrone, PA 1260 Posts Member since: 2007/12/30 0:00	If the bottom end of his engine is healthy it does not need rebuilt to make more power. The top end and the exhaust is the restriction. He could bolt on good aftermarket heads, decent cam, HSR or miniram intake, headers and dual exhaust, bunch of other small supporting mods, and make 325 or so rwhp with that stock bottom end. Just depends on how much he wants to spend and what he wants to do with the car. Or he could do the right heads/cam to work with a severely ported crossfire intake and have horsepower likely in the mid 200's at the wheels with alot more torque than that, and have less money in it. And who doesn't like the underhood look of a crossfire??? It all depends on money to be spent and uses of the car.

Would that old girl gain power from roller rockers, or not worth the effort? Some cheap and easy suggestions on upgrades would be appreciated. Then again I wet myself every time I drive it anyways, so more power shouldn't matter Fixed it.

OK then: Quote: pappyfreebird wrote: Ok, so how much rpm will my stock 84 L83 take? 6200 Quote: I don't like walking or spending money. Well, we have 2 things in common. Quote: Would that old girl gain power from roller rockers, or not worth the effort? Maybe pick up 10 or so hp with 1.6 rollers, closer to 20 if you port the intake and do headers/dual exhaust. Quote: Some cheap and easy suggestions on upgrades would be appreciated. See above posts Quote: Then again I wet myself every time I drive it anyways, so more power shouldn't matter I guess we only have 2 things in common, not 3. That feeling will go away, and you will need 100 hp increases to make the feeling come back. It will last 6 months, then you will need another 100 hp increase to get your fix.
