Help me build a reliable 500 HP 446

67 440 stock bottom end. Old school TRWs. If i remember right are .022 in the whole. I could be wrong, and will verify before going forward. I am selling my 906's to go aluminum. What heads,cam intake and carb will make a flat TQ curve and 500 or so hp? I like the $ of Stealth heads. Kinda like the idea of roller cam.

With flat tops and aluminum heads, it will be hard NOT to make 500 horsepower.

Mild port eddy or stealth heads, 275HL cam, 1.6 rockers, .017 thick cometic gaskets to give you some quench and a good 950HP carb. Should make right at 500HP give or take 5.
