Hey, I have a new set of Cima pistons and cylinders. I believe they are for a stroker. New in the box and covered in cosmoline. Rings are there too. Thanks for looking.

"A"s will measure over 1.1" from piston top to the top of the wristpin hole, "B"s will be ~.9"

Thanks Marc, just measured. .9 from top of piston to top of the hole.

Confirmed to be 90.5 "B" then, for stroker crank. Compression height (piston top to wristpin centerline) of ~34mm. What are the ring thicknesses? From the photos it looks like they're the "late" 1.5x1.5x4mm.

"A" stock-stroke compression height is approx. 39.6mm.
Early 90.5s with 2mm compression rings had smaller cylinder O.D. - 97mm head, 94.4mm case.
Late 90.5s have the same O.D. as classic 92s - 98mm head, 96mm case.
To the best of my knowledge only the late pistons were produced with the graphite skirt coating (I've never seen a coated early piston, anyway).

Looks like they are headed to the land down under.
