.30 over Piston need advice
I am building a 355 and need to keep an OEM piston. I.E weight and design. Can I get recommendations on pistons that meet this requirement? I am racing in the SCCA hence the restrictions.

No doubt. Also, any good parts store should be able to obtain stock replacement .030" overs. Make sure they are quality hyperutectics like the originals. Much stronger than a standard cast piston. I'm using KB hypers but I'm not sure if they make a stock replacement, but they may. They have a selection of pistons that will boggle the mind! http://kb-silvolite.com/index2.php

Lunati, Ross, Venolia, CP pistons and I beleive JE all manufacture a OE spec (weight limits) forged piston that is NHRA legal for stock eliminator drag racing. These pistons would be legal for your SCCA class rules as well.
