Design for my blower engine.

Did you call United and talk to Marco? He might can find another Chevy slug that could give an even lower static compression ratio. Then you could really spin that blower. That part number was one he came up with in about a five minute converstaion that he kew would FIT for sure. You can use that same compression height and look around for something with more piston volume if you want to go lower. Marco is they guy to talk to, though. He's real sharp. Your build sounds real good to me. It oughtta be real nice.
