Thank you Still wondering on the pin height differences though, does anyone know about that?? >_<

I've heard 2mm is the max overbore an L engine should ever have... I thought a stock L28 piston was only 0.040 larger than a stock L24 though? Please correct me if I'm wrong. I would do that as well, but the walls have been bored out .020 already, and It looks like Northern only has stock sizes.

I'm having the block bored out to fit the new pistons

I currently have a '71 that I'm building up, and I plan on buying a mild cam/spring/rocker kit and forged pistons... I see L28 pistons all over the place and not much on L24's. I've heard that an L28 piston will give you a lower deck height, thus reducing compression and increasing valve clearance. My questions are this: Is what I'm being lead to believe true? If so, how much lower is the deck height over an L24 piston, and what would the new compression ratio be? Thanks Steve
