420 in a S2k is nuts.
I dont know where some of U guys come off saying "only 420hp with all that"??
Its a stock block, thats great. Most S2k's NA make like 190Hp LOL!! My friend boosted his with a greddy kit and only made like 315hp.
As long as the tranny and rear end hold up your straight, I hear there like glass on those cars. But mad props to you! That shit must fly!
