Thanks. I'll be following the same specs that my cousin used in his 500hp 440.
I'll actually be using his 915 heads with 1.81 exhaust valves, gasket ported intake and exhaust.
Forged flat top pistons and crank. But I'll be using a few different things.
2x4 intake, Carter primary and secondary AFBs.
Mancini try Y headers.
