Stroking a 5.7 vvt engine

[jknappen]

Obviously I would delete the MDS but what is a good setup for forged pistons, rods and Crank. Which ones come already balanced and ready to just drop in and go? Also, when stroking to a 392, do you have to bore the block and which heads and intake are good to run?

May want to contact mmx for your hemi questions. They’ve got a full selection of parts and should be able to answer anything you have to ask

I’ll 2nd what crazykid said. Contact MMX, they have a wide range of options for the hemi engines. I have one if their drop-in forged rod and piston combos in my truck. It has been great with no issues, other than it’s a little louder than a stock hemi due to the nature of forged pistons.
