Just received a set of pistons for my Chevy 396 build..obviously they have been sitting on a shelf for 25 years.
Box says 86 but who knows...anyway looks like a rough casting,not polished like the pics you usually see.
I need to finish the pistons somehow?
Also 3 pistons seem to have a loose fit of the piston pins,as i can push them through the piston with finger pressure.
.990 is the correct pin size...the loose pins measure .989...1/1000 gonna make that much of a difference?
I called Rock auto for 3 new piston pins. :
Thanks.
