hey guys heres the deal. i have the chance to get a cadillac 500 with 400 tranny for 350 bucks. i love my lil 383 stroker but my dad has raised me to love speed. i think ill be able to sell my stroker for 2 thousand worst price but how much would it be to get the 500 to get above the 410hp mark ( thats what the strokers at). i know ill need a lighter crank but what else ? i already have the 4 core rad to keep it cool and i cut my own exhaust so thats np. and has anyone done it before? and the cadillac motor is garanteed running. thanks guys
