About $6k + - should be enough.

Why reinvent the wheel. Go over to the Airflow Research website. They took a Ford SVO crate 393W shortblock, tweaked the cam with a slightly warmer CompCams Hydraulic roller, bolted on a pair of their 185 heads, and dyno'd it. 509 HP, 537 FPTQ. Not a typo, that's a "5", not a "4"! The carb was a 750 Demon DP. (By comparison, the original 427 8V installed in '64 - '65 Galaxies & Fairlane 500's [and some Cobras] were rated at 425HP, and 470FPTQ with 11:1 compression. The 428 "Police Interceptors" fitted to most street Cobras were rated at 335 HP, and 480FPTQ).
