J heads upgrade

400-ish hp 340 with 3.91 gears = lots of teenage emulated fun in an A body...

You won't need a whole lot of cam to make that, if the engine is properly configured. Maybe 230-240 @ 050? If even? I smell solid flat tappet :) ...unless you need to go hydraulic.

Did you really ever place any limitations on this build? Like, what can you not do? What attributes can you not deal with? How much money can you not spend?
