Talked to a gentleman at the Dart booth this year PRI about the G3 block. They had experienced porosity in the cam tunnels. Fixed that. Supposedly, there are a couple in the hands of builders set to dyno test completed engines. Sounds like availability is a long ways off yet. I'm in total agreement with Rat. Is they're behind on Big Chevy stuff, when the hell can we expect the G3 stuff? He did say that there was a LOT of interest though.
