6.4 PISTONS

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.

6.4s are a4.09 bore std

Mahle(sp) has some also ,

I meant the chambers to figure out the compression as he said he wants to be at 11.3 to 1.

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.

Prefer not to use up my heads , but will be contacting DSS . Thanks.
