Its a 393 stroker , 4 v closed chambers running on pump gas ?
Thanks

@98octan , I mean.
I heard its about 14:1 and to much :-(

I have a piston builder that will make ANY piston that you need and ANY bore that you want.
These pistons are so custom that YOU specify the bore that you need for your block. It isn't even necessary for the pistons to all be the same size.
All 8 can be different bores.
The pistons are $600 plus the rings.

ballpark guess using 62cc chambers makes 11:1
a 13cc dish piston gets it down to 10:1
Open Chamber heads milled to 72cc's makes the same 10:1 and flow better
or modify the closed chambers to a 72cc volume, unshroud the valves and leave only 1 quench pad. chamber pics here http://pantera.infopop.cc/eve/...0045562/m/6700079993

Hey Doug,
Can you PM me your piston manufacturer/contact? I'm still looking for one (1) Probe SRS forged 383/408 stroker piston for my Cleveland that swallowed the air cleaner stud. No one has these things, and all other stroker pistons I can find are for +.030" bores. My block is only +.020", and I'm not willing to unnecessarily remove more material from the thin-wall 351C bore just to accommodate a lazy piston manufacturer's off the shelf pistons. So now it's time to look at having a set of custom pistons made.
Thanks!
Garth
My 391C (original owner had flat top Probes pistons and closed chamber which raised compression to 11.5 to 1)
I waited for the right opportunity and purchased open chamber 4V heads with SS valves, adjustable valve train hardware and fresh valve job and brought comp. down well over 1 point for more streetability. My next motor which I'm currently putting together is a 4 bolt block that cleaned up and honed at 4.017 and Diamond piston will gladly custom build my dished pistons for a streetable 10.5 comp. with closed chamber heads and a .14 cc dish.
