This is from a work order Jan '02, so i can't say if the company info is still valid. Anyway JE Pistons,15312 Connector Lane, Huntington Beach, Calif. You might be able to reference what they did for me with the job order #298446. The phone number shown is (714)898-9763. They also show a piston part # of 196722. Maybe it's a guy thing, but those pistons were just beautiful.
The piston weight is 445 grams, and as mentioned before, comp. ratio is 10 to 1. The cam was reground by Isky Cams for 270 deg. duration and .465 lift. For grind, they show '270-Mega'
