i called je today. the numbers on the underside they said are simply casting numbers and they cant tell what they are from that alone.

i.e. they machine more than one style pistons from the same casting numbers i.e. lot number.

could you take a pic of one of your pistons. Wondering if mine look the same. Particular the shape of the top surface and the complete side view.

ed,

"Casting number" ? Just an expression, I guess - they are forgings, aren't they ?

I have one or 2 xtra J&E Extreme Duty pistons, so I will see if I can get some numbers 4 U.

yep wrong words there.

Reason i would like to see is i think i should do whatever is necessary here to be sure these pistons didnt raise the compression ratio.
the way things have gone so far I wouldnt be surprised by anything.

The piston i have dont look anything like what i see im the new je catalog.

The machine shop i just dropped things off at is going to find out to be sure. Otherwise i may have to buy new ones to be safe. Or ship one back to JE to find out.

Just wondering how much J&E Extreme duty pistons cost each. At least i think that is the correct one for out application. (looking at page 7 of their 2002 catalog)

ed,

I have J&E's # in CA. I just talked to them yesterday - it is 714-898-9763.

Supposedly my CR will be 8.5/1 as opposed to 8.33 stock - NBD. The Tech guy @ J&E said that the SRP'S, which is their high volume production piston, has about 5-8 % Silicon in it, so it will be more brittle than the Extreme Duty's, which don't have Si.

I guess the ED's R pretty much their top of the line piston. U can get a price from Summit - I understand the one we want is 131-635 for the .020" oversize piston.

we run the 131636's in the high boost stock block .030 motors. Most of the bowtie block pistons are custom, b/c the next size up is a 4.155. We have also been running the spherical dish piston with good luck.

FYI, I will match or beat any price on JE/SRP pistons.
