90.5 X 69 JE or Weisco's ?

Hi just wondering if anyone has ordered or has seen a good forged piston with the 39.6 mm Compression height ( or close to the "A" Style compression height )
I have a customer that want some real RPM's......
Gonna give JE a shout tomorrow but was hoping someone has already been through this can throw me a bone.....
Cheers,
Darren
P.S. I know I could use the B style but the motor would be so damm narrow the carbs won't clear the fan shroud with out a ton o work....

Hey Darren, call Nato at bros machine shop. He's ordered JE and CPs. The CPs would be my choice. I have a set of them in 92mm for my next build. They are nice!

Hey Darren, I'm interested in your build!! If your going custom maybe try JE/weisco. If you want cp you have to go through a dealer, not the case with the others I don't think.

Darren.
2 things.
My choice would definitely be JE´s, as they are about 50 gr. lighter than the counterpart. AND you can get JE´s with 1 or 1,25 mm top rings.
Next. You may want to consider lowering the pin height, eventhough it "creates" some machine work on the cylinders. You can reduce the piston rattle significantly and thereby free up more hp, by doing that.
