well it would be a high compression motor with nitrous. i talked with texas speed about the cam motion 256/267 cam and that FMS godzilla cam also has my attention

as far as power...what do the 408's usually put down NA with a healthy h/c setup? 520 or so? i would plan on starting with a 150-200 shot

They will range from 440hp to 520hp or more depending on the car, dyno, and setup.

With your setup and also planning to spray I would go no less then 42# injectors. Ive got them on my car with racetronix PnP system and its made over 620hp with more left in them. The car never started running lean.
