3.1 Gen II pistons in a 3.1 Gen III engine

[Axelsmancave]

Hi All,

I was wondering if I could use older style gen II 3.1 pistons in a gen III 3.1 engine. I think the only difference is the coating. Anyone have any experience with this?

Thanks

Yes however there are a few other differences that ill cause some lost performance. The compression height is shorter and the dish is larger so you will have a drop in compression. 8.67:1 with .060 headgaskets and 9.08:1 with .040 headgaskets.
