I have decided I am going with different pistons. 12:1 is just too high with boost. So I am getting rid of these.
Federal Mogul H562CP .040 oversized.
These are for a 3.1 iron head motor and is .040 oversized. With iron heads the compression ratio will be approx 8.8:1.
The skirts are coated with a teflon liner to reduce friction.
These retail for $30 a pop or about $180 for all 6. I want $110 shipped. They are still brand new and in the box.

these are 3.1 iron head pistons so I calculated the CR with a 3.1 crank.
You can't use these with a 2.8 crank unless you get custom rods. Compression height is stock for a 3.1 piston. I want to say 1.45 or something like that We had a chart posted here recently with all of that stuff.
But its the stock compression height.
With iron heads CR will be approx 8.8:1
With aluminum heads the CR will be abuot 11.8:1
Thats way too much for boost so I want different pistons for my al heads.
Yes bore size is 3.542 or there abouts with these pistons..
And Jon, you can lick my Ballzack
