Wow very impressive, I have heard of 10:1 compression motors being turbod, the only thing I was unsure of was good dd car. Thanks for the clairty youve made. Ill prob go with a 10:1 but really want at least 350-375 hp, if and only if u dont think I can do this on pump gas let me know and ill go alil lower, but as stated before about main and rod bearings what would u use in a high hp motor.
