NEEDED ASAP - PISTONS FOR 4.1 STAGE II HEADS!

[Squid4life]

So the pistons I was planning on using will not work for me, and I don't have the time to wait for JE to cut some new ones unfortunately. Anyone have any sitting on the shelf, or awaiting a build that could wait a little longer?

I am running 3.59" stroke and a 6.5" rod, so CH is ~ 1.196 to a max of 1.2

I have two blocks and can run ~4.010 or ~4.030


I know this is a long shot, but need to try just in case. Any help is greatly appreciated.

If need be, possibly... Need 9 - 9.5:1 cr. What you got brother?

they have a bit of a dish coming in at 35cc, with a 48cc head i think the compression calculates out at 8.852 on the slugs, but thats with a 6.650 rod on stock stroke. using your rods on the increased stroke with these pistons i think it might get you where you need to be with the S2 head depending on deck/gasket/clearance variables.

I need to confirm bore size..... but in your range i believe.

Bore, sure yet 100%
CH, 1.19
Dish, 35.5cc

think maybe they will work?
