Re: piston weight wl

Jib,
I just weighed a .020 OS WL piston of the later type with thin rings and it is 380.7 grams. An NOS K piston in .'070 OS weighed 376 even. i have some NOS std Mil Surplus 45 pistons but don't want to open them until I need them. I'll try to look later and see if I have one with the cosmolene off of it!
