Ok, so basically everything is done today. In terms of taking care of parts. Finally got the rods figured out. Eagle is going to supply my rods. As it turns out, the 2.2L rod is the same length as the 2.0L rod. The bearing diameter is also the same. The only difference is the pin bore is smaller (21mm vs. 23mm). I talked to Tom Shomba (sp?) who has an 1150 hp RWD Cavy and works at a local dealer ship. He said for some of their less hp motors (650-700 hp) They use the eagle rods and have the pin bore opened up. I'm going to order a GM intake cam blank, and have my stock exhaust cam reground. Tom said with good exhaust flow the exhaust cam is not as important as the intake cam with a supercharger. So I'm doing a pretty radical intake, and grinding the exhaust as much as possible. Centerforce clutches is also supplying a twin disc clutch. So basically, no I just need to get the head ported, crank machined, and neutral balance shafts made, and I can put this son of a bitch back together!!!

I don't know why everyone says Neutral Balance Shafts aren't good for a daily driver. Witt has them installed on here, and I have them. You barely notice any vibes. Plus you get faster revs such as a lighter flywheel. If you already have any type of solid mount, you definately won't notice the vibes at all. Witt has just the Intense inserts on his lower tranny mounts, and he didn't notice any difference.

Well, I talked to him on the phone, and he has an 1150 hp cavy with a 2.16L ecotec, so I'll take his word for it. He also said they are running 117 degrees of lobe seration on their car. He also said I don't as aggressive an exhaust cam as I do intake, as long as I have a good flowing exhaust (which I do).

BTW, his 1150hp cavy is gonna be more like 1300 once he puts on his bigger turbo setup.
NHRA authorized it!! You are going to put on the adjustable cam gears too right? Ain't that what he said?
