Help Needed - Budget 318 Sprint Car Build

Don't take my comments the wrong way, but this sounds like a recipe for disaster. Your wanting to run parts that are WAY out of there design limits. The proper valvetrain alone to run SUSTAINED 7500-9000 RPM in a mopar smallblock are going to be very costly, and you would need a bare MINIMUM W2 or better heads and a "R" block. That's a few of the about 50 things wrong with your plan.
