Re: Hello everyone! How much HP is too much?

Thanks for the welcome. Most of you seem to think it will not be too much HP. I don't know a lot of automatic transmission talk. What does it mean if someone has stall converter? 1971ls6 mentioned a 114 lsa and a power band to keep the wheels from spinning. What is that?

Also, will a rear end from a 327/210hp work with a 383/510hp?


Thank you guys!

The engine is a brand new 383 stroker with 500hp (never been driven). The trans is a brand new TH350 Stage 2 Short Tail. Also has Hotchkis Sport Suspension 80015 TVS system for 1967-1969 Camaro and twin fan aluminum radiator and Flowtech headers. The engine and trans are in but the drive shaft is to short because he changed the trans. So he says it needs a drive shaft and the radiator installed and it will be ready to go.

My question is, after I put it all together is the 500hp going to be too much for driving around. He didn't say what size rear is in the car.

Thanks for any feedback,
Rusty
That is a very subjective question. To some a 500HP 383 might be considered mild. Others might think it is too radical. First off have you ever owned a high performance car?

That's good, you have some experience with older cars. If it does make 500HP it will have a fairly lumpy cam. If it has a stock converter you will need to change it. Power brakes may a bit of an issue at low speed in a parking lot. Your car should have an 8.2" rear. With a few aftermarket parts they can handle a bit of abuse. I have friends running 12.0's and little quicker with modified 8.2's.

Unfortunately, you can't test drive it but you can ask the owner for the following:
1. Cam specifications or manufacturer and part number.
2. Converter information. Diameter, manufacturer and stall range?
3. Rear end information. What gear ratio? Stock axles? Posi?

Re: Hello everyone! How much HP is too much?

Steve, It's going to take a few days to get those questions answered. If he knows the answers. I think the owner travels a lot. Everytime I try to set up an appointment to see the car he is not home. I'm sure the rear is the original that was in with the 327. I would bet it is a open stock axle. Am I allowed to tell you where you can find it on the computer? I don't want to get red flagged for doing something against the rules.

By the way, what is the stall range?

Others have posted links to cars they are interested in purchasing. I don't believe it is a problem. High performance converters usually list the approximate stall or range, like 2,400 or 2,800-3,200.

Also, welcome to the site!

Re: Hello everyone! How much HP is too much?

I would say much more than 650ft/lb tq is too much for the street. Stop this stupid HP non-sense, it's a street car the OP is talking about.

I have 560ft/lb tq @ 3,000rpm, and I'll tell you what, unless you have a *proper* and I mean properly setup aftermarket suspension and run drag radials, even that is too much on the street.

IF you have a professionally sorted aftermarket suspension (that means hours after hours of road testing and tuning) for putting down the power with some great drag radials, then I would still say 650-700ft/lb tq is the most you would ever want with todays tech.

If you wanna act like a clown and smoke your tires and have the FU money to piss off on said tires, then the sky is the limit.

Re: Hello everyone! How much HP is too much?

If you love the sound of a wild cam and like knowing the power is there, but don't intend on using it, 500 hp isn't a big deal. I run just over 600 hp, 575 torque with a 5 speed manual and yes, it idles fast and rough and doesn't have much vacuum at idle, but it's as tame as any street car (well maybe not quite) until you lay on the pedal. If you have no experience with that much power and intend to use it anyway, that could be dangerous. If you want a nice calm cruiser that doesn't shake or buck, you might want to go to a milder cam and tune it down a little. Was the 510 hp on an engine dyno? or an assumed rating? I realize that torque is what gets you down the track, but if you're over 500 hp, I'd be surprised if you're under 450 lbs. ft of torque, so you've got enough to be dangerous if you're not careful.

The seller said he has a video of the dyno. That's all I know.

Re: Hello everyone! How much HP is too much?

The bigger problem i see is not enough gears! Th350 if it has too much rear gear it will be no fun cruising for long

Scott from NJ. Stay thirsty, my friends

Feather-light suspension, Konis just couldn't hold

Steve, This is the web site of the dyno video for the engine. Copy and paste.

Re: Hello everyone! How much HP is too much?

The engine dyno result is 419 hp 447 torque

Don't know where the OP came up with the 500 hp for this engine.

Maybe I'm confused?

500 at the crank, livable. 500 at rear wheels, stupid for a street car. Especially a cruiser. What's he done to the frame to handle that? Subframe connectors so it doesn't twist? I assume he didn't do all the suspension add-ons without doing something to tie the subframes together. Check it. What rear end is in it? 8.2 will not last. The transmission case is the weak point of a TH350 when exposed to high power levels.

383's are torque motors. Torque is what moves you on the street. What heads are on this engine? Port size? Sounds like a cam that is too hairy for a street 383. Need to find out what cam is in it. Mild cams and 383's make for very happy and satisfied owners. Especially ones that are just cruising their car.
