New guy to big block world, need a 400HP 383 Recipe

Welcome Blak92! Well, it won't take too much to hit your 400hp target :) First, you'll want to grab the Schumacher headers & engine swap brackets (engine-swaps.com) that fit right in the Cuda (usually a used set on here); the Stealth aluminum heads are a bolt on (440source.com) & reasonably priced but not necessary for the target goal- any 383 head will do; a nice Comp Cam kit around the old standby 292/509 range will work; I'm a fan of lightweight forged pistons- budget-minded Keith Black's are good; Also a fan of new rods- I beam's from Scat or Eagle; finally a RPM Edelbrock intake will be the best topped with an AED or Eddy performer carb of 750 cfm. This combo should make 450hp easily with the Stealth heads & 410hp with stock 906's.
