Thanks for the info.. I am trying to determine if my car has the L-88 pistons in it without pulling the engine. I have scoped the pistons and they appear to be the big dome ones and have a number (hard to read)stamped into the top of each piston but those numbers you gave me do not match what I THINK I see. The car has open chamber 990 heads on it and a pretty radical cam so I think they are L-88 style.
