Sigh. Well, I read the GCR again and am inclined to agree that the Wiseco piston's probably do NOT match closely enough to be legal. I was focused on making sure that the compression was legal and did not realize that the pistons had to match that closely. Dangit. I'm stuck for the moment. The fellow building the engine sent an email to Bildon several days ago. I sent an email to Bildon yesterday. We haven't had a response. I have called Techtonics and they don't have any stock pistons either. Techtonics suggested cutting down a VR6 piston. I now suspect that this is illegal too.

Is there a readily available LEGAL piston that can be modified to produce the proper compression? Any other ideas/suggestions would be very much appreciated.

Thanks for the help!
