They,Mopar, have said they NEVER re-cast ANYTHING without revisions/improvements. I hope one of those is a cylinder thick enough to 4.20 ish. THAT would be a step in the right direction. Maybe they have applied some of the same cooling tweaks as the Hellcat block. The old 6.1 blocks were simply assembly line blocks left over when they switched to the 6.4 in 2010-11. I have no desire to buy a VVT block of any kind.



what is wrong with the vvt blocks?

Nothing if your name is Steff lol! Cams are expensive and timing chains are subject IMO. They need the VVT feature locked out or deleted for the hot rodder. Quality of them is good to go though, just more of headache and $$$ for no advantage other than availability.

Mopar to the bone!!!
