I have a BGE on its way to me so i will keep u updated. I think its in the hemi vendors best interest to not let on that the pistons and rods are any good. Their livelyhood is selling pistons and rods always with the scare tactics of no more than 5 psi boost on 6.4s etc. Or you need pistons and rods to make power.....Quite a few cars locally on standard pistons. Low 10s in a 300 with a 6.4.

Heads are cast same as a hellcat... same material andnports just intake bolt pattern differs
