Looking around for pistons i don't see anything for stock stroke 6.4's .
I'd use something like a Molnar rod 6.200 length with .927 pin . I'd like around 11.3 comp so the Mahle drop ins won't work . Am i going to need something custom .

DSS Racing Pistons has a set that says 10.9 to 1 with 72cc heads... I have no idea what size 6.4s are.

340 barracuda, 01 Ram CTD, 95 Ram, 04 Ram, 85 Daytona turbo Z

Truth has no agenda, but those with an agenda make their own truth.
Some of us are so open minded they only see their View

6.4 heads are 73-74 cc . That gets around 10.9 with the manley 59880C piston , for a little under $700 a set, it's tempting , but a little more comp would be nice .

Mill the heads some, I took .020 off early 5.7 hemi heads and didn't have to change anything else. The dss pistons are around 550 a set.
