I am switching over from a NA/N20 setup to a FI setup and from my calculations, going to a 72cc head will bring me down to 10:1 compression. I currently have a 383 (3.905 bore x 4.0 stroke) with diamond pistons that have -2cc reliefs. I am really trying not to have to switch out my pistons, since this motor is brand new. I am only looking to make 650 whp at this point since my fuel system will only be a racetronix 255 pump and 60lb injectors. I was also told that having a set of LQ9 heads CNC'd to 76cc would not be recommended on a small bore engine such as mine. All help is appreciated.

I would just do dual intanks which should handle 700rwhp easilly enough.
Or a methenol kit.
