As I stated, I know their out there. Yes hes also gonna need some big breathers as well. $$$ The original OP did not state enough info as to what the primary use of said motor will be but unless its drag racing and pump gas is mandated I think running that high compression on PG is asking for trouble. If its drag racing and your pulling gas from the same Sunoco pump every race than ok but I had a 700hp high comp street motor years back and picked up bad gas to many times. If its me dumping 20g,s into a PG motor today I'm staying under 10:5.1.
