Has anyone fitted a 570 piston to the ‘09-‘12 FE450?
Without measuring I can see about 2-3mm more deck height with the 570 piston. Looking at the crown design it looks to be fine to remove the difference. It will put the comp ring closer to the crown. Is this a problem? Do we have much squish to play with? Crown and combustion chamber would need to be cc’d. Is the outer dimension of the 450 sleeve the same?
Cheers guys.
