I know that they use the Hellcat block and heads, but what about the rotating assembly? I'm guessing that they have a forged crank and forged powder metal rods, but are the pistons forged? I've heard that they are but haven't been able to confirm. Also, what are the cam specs? Likely using a 5.7 cam?

Dodge says the pistons are forged however all the Hemi vendors say they are not

The BGE block is the same as Hellcat but painted a different color.

The crank is a forged crank that is the SAME as the srt forged 6.4 crank from the passenger car. This was confirmed by a Hemi vendor.

I would treat the BGE just like a srt rotating assembly- great crank but rods and pistons are not suitable for a serious performance build.

Ah well, I thought maybe the BGE 6.4 would be a decent boost ready junkyard engine if it had forged slugs from the factory

Heads are not hellcat, Hellcat have larger intake mounting area.
6.4 Short block will take some boost just make sure you open up the top ring gap. granted your not going to hunt down any 405 street outlaws with a stock BGE 6.4

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

Same casting (ports, material, heat treating, reinforcements etc), but different bolt pattern.

Originally the crank was a different part number to the srt 6.4 but now i think they are the same. I should have both an srt and a 2014 (1st year) bge pulled down side by side to compare cranks, rods and pistons

Thank you!

When i say BGE are cast same as hellcat i dont mean that they are the same casting just with different intake face drillings they are not.
However they share the same casting strength improvments but the bge has no allowances cast into it for a hc intake pattern

IF you get the chance to cut both heads open, the Hellcat have more material under the Intake valve seat and waters passages around exhaust port are larger.

The BGE has a different part # stamped in the top of the piston but can not come up with anything on the #. I bet it has forged pistons!!!
