I'm acquiring a set of stock bore, stock port virgin cylinders and having them ported along with a +4 long rod set up. I purchased a matching, no damage 2000 model year case. Mine has chain whack and a bad crack in the bottom that I had welded. I case ported the outside transfers to much. I went down to 4mm wide surface. I had a hard time getting the base gasket to seal. I had to double side yamabond the gasket to get it to seal. That's no good for long term reliability. I'm sending my bottom end in to the builder for them to disassemble and transfer and check parts going into the new cases. Getting the shift shaft mod done, starter idler bushing will get checked and everything else that may have a problem. Talking with Jeff at FAST he said that the lower case studs have an issue with air leaks from time to time. I'll make sure that mod gets done as well. Jay threw a lot of info at me and I like what he had the say the best out of everyone I talked to today. He suggested custom pistons as a possibility. He has a set coming that he's going to do some testing on the dyno to see how they work. I'm hoping to get this done before mid June for the Silver Lake ride. I'm not sure I can pull it off or not. I also have to fix my blaster for my GF. The case got whacked with the chain. So mo money, mo money, mo money.
