I used Diamond pistons on my 4.15/6.86.. 477. CompetitionWedge supplied them and went with 9 1/2 cr because of gas, less weight(?) and decked block. Compression works out to about 10.97 to 1!

Rods are 440source



Diamond will also probably get my next order as well for Hemi pistons. They have some really nice dedicated hemi stuff with comparable prices. We have built at least one hemi with their pistons, and they are nice and light. The JE's I have are quite a bit heavier.
