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.
