    :eek:
    I agree lmao

    I will say, my big block made 500 horse from 5000 to 6000 and 550lbs of torque from 4000 to 5500.
    This was before I swapped intakes, so add 30 horse and 20lbs of torque.
    It was around 6000 for everything to get it in the car.
    cheaper than an LS AND will out run them ;)
    How do I know?
    I guess the turbo vette had to learn(this was a friends car and yes we were racing) It was a 5.7 corvette with a single turbo. I pulled him everywhere.
    A bunch of friends saw this(we were on his private driveway) and asked me if I had my nitrous hooked up, popped the hood and I didn't even have the plate on yet.
    LS guys love their PEAK power, but when you look at the curve, the peak is REALLY high and the average horsepower is low because of it. I love the LS platform, but if I build one it would be a stroker.

    Let's see a LS motor keep up with 565 BBC or even 632 BBC

    When we make more power than you?
    Yeah sure.
    I already told you I would out run you, and you didn't say anything.
    It's okay, you can live in your own world.

    Big blocks are still kings, with turbo LS the runner up behind them.
    You have a N/A Ls which is nothing special.

    Rob - If you're looking to autocross the car building a 500HP stroker small block should be really far down on the list of things to spend your money on.

    You'll make much bigger gains with tires, suspension, brakes and driver training.

    In fact, I would expect that the power increase will slow you down at this point.

    To plant that much hp you need to check out www.calvertracing.com . I'm running their complete drag racing suspension set up and with 275/60-15 drag radials my Camaro hooks very hard on the street now

    Made a huge difference on my car.
    I might go back to the drag look and buy some drag radials, but even with 18 inch wheels, my car hook 100 times better with just the traction bar!

    If you want to autocross the car, you should focus on mid-range power, period. And, your suspension, chassis, and brakes should be a focus, not necessarily the engine. Check out the Suspension forum...lots of good advice there.

    Last, if you really want to play with the notion of 500 RWHP, get out your wallet. That number and "fair budget" do not go hand-in-hand. An SBC motor making that kind of power (N/A at least) will cost you close to $10K...and I wouldn't even bother trying that with a stock block. Lots of ways to get there obviously, but they'll all cost a lot of money and you'll also have to ensure your transmission and rear end can handle that power.
