Quote: Looking at 6.4 block and apache heads for a turbo motor in the 1,500+hp range, good idea???
IMO yes. All my info is from what others have stated and engine article i've found in mags. As of right now I'm a closet G3 guy. Soon to be a veteran The 6.4 is a stronger block than the rest. IMO the Hellcat is a stock 6.4 that has been machined differently. The only problem I see with the apache heads is the material they use for them. In high boost I believe the head will start to warp. At what level is the real question. Matt
