Question Anyone hit 500 big ones?

I've got a 68 camaro that im doing body work on all winter. Well its got a Small Block 350 from summit racing, came with the car when I bought it. I want to hit 500 wheel horse with this car, has anyone achieved this with a 383 or 400? I know I'll stroke it to a 383 at least but im just throughing it out there. Give me some feed back on this,im thinking about doing dual quads with afr heads but ide like to see if and how people are hiting this mark with a small block.

With a supercharger should be somewhat easy ?

N/A going to need a lot of cubes and compression.

Or.... built it for about 250 shot of giggle gas.

Re: Anyone hit 500 big ones?

Mike..Hopefully everyone that responds recognizes that you are talking rear wheel hp #,s vs crankshaft #,s.I know of a sweet streetable 406 that knocks down 550 hp that I could share..but would not put up 500 hp on a chassis dyno with drivetrain losses factored in.

Re: Anyone hit 500 big ones?

You will need to build a 427+ cube smallblock to do get 500HP to the tires N/A. Have you driven a car with power close to this level?

Re: Anyone hit 500 big ones?

I have put together SEVERAL 485-ish at the crank and its fairly easy, just use the right combo of parts....but 500 to the wheels? I am aiming for that for the 55 so heres my "paper" build:

motown block AT LEAST 434CI - may try the new SBC 454 Mitchell stuff
AFR230< ported/polished/blended - BIG valves
Roller valve train 630/630 lift, 290-296DUR, ground on a 109
Try to hit the 11.5-12.5:1 CR
Motown intake matched to heads and an AED1050 carb. As i get ready to do this Ill start doing a lot more studying and reading/researching.
My guess is this would be REALLY close to 480-510 to the wheels. However, the closer you get to 500 the harder it gets to make and and build it. Building a 400hp stroker and building...even a 475hp stroker are 2 COMPLETELY..COMPLETELY different animals.
Ill be watching this thread....I can build some mean SBC's but the most Ive done to date was a 421 with 13.6:1CR and a heads/intake.carb combo that would rival and F-5 tornado. It was knocking on 700hp with a little gas. and by no means was it something that you could cruise to sonic and back.
Good luck!!! Im watching...

Re: Anyone hit 500 big ones?

IF you have the means, this is very acheivable with an LSx motor with very few mods and gets good gas milage to boot.

Smile Re: Anyone hit 500 big ones?

Factoring a rough guess of about 20 percent more for the powertrain losses, you will need 600+ hp to get 500 at the wheels, imho.

Probably a very well thought-out 427 SB will do it. It will probably be onna those high-spirited cam-cacklers unless you blow it!

Your saying 600HP naturally aspirated to the tires? Post em up if so.

To get 600+ to the tires you would need to make 750+ at the flywheel. That's with 20% loss through the drivetrain.

i would say yes if going through an automatic trans with a big converter. i would guess that it would be 12-15% with a manual trans.
