Wanting 500 hp (or close) out of a stock stroke 360

You need more cam, more compression, more cylinder head, more intake.

More cam= something in the 260 zone @.050, .600+ lift

More compression= 12+ to 1 or more

More cylinder head= fully ported Eddy's that flow in the range of 300 cfm at .650 lift

More intake= Eddy Victor or better

You MIGHT be able to do it for a little less than that, but that's where you thought pattern should be.

The other part of your thought pattern should be to stay right the hell away from street racing. Yeh "Street Outlaws" is fun to watch, the only thing missing on race night is grand stands and a concession stand, and so far no one has died.

You want that street race vibe....just go to a track that sponsors no prep racing.....then you can figure out what it takes to beat those LS clowns.
