Pistons!
My pistons finally came in from Butler. Heat barrier top coating and anti-friction skirt coating. LS ring pack (1.2mm,1.2mm,3.0mm)With the 94cc Edelbrock heads that SD Performance is doing for me ( 325 cfm with 5/16 stem Manley 2.180 intake valve and a custom 11/32 stem Manley tuliped 1.740 exhaust valve along with small dia. dual valve springs to further reduce weight and T-washers installed) and .056 Cometic (Luhn) head gaskets we'll be right around 9.15:1 - 9.20:1 compression. Rotating assembly went off to the machine shop for balancing today.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
