Yeah Ive got exhaust wrap to wrap all the hot pipes in, and a turbo blanket for the turbo, should keep anything from melting.

Can see the blanket here from when I was mocking everything up on one of the spare 5.3s

Yes, its about 3/4" below the crossmember.  If i had to do it again i would have used the Holley pan.

Nope they are cast, but it doesnt bother me considering what I paid for them (<$350 for all 4) Jegs sells them as their brand, but they are made by Vision wheel http://www.jegs.com/p/JEGS-Performance-Products/JEGS-SSR-Star-Wheels/3663732/10002/-1?productId=3663732&N=0&Ns=P_Margin%7c0%7c%7cP_SKU%7c0&Tab=SKU&storeId=10001&catalogId=10002&langId=-1&Nrpp=180

Got the exhaust done, 4" from the turbo back. My plan was to have it exit right in front of the rear tire but i didnt have enough 4" left to get it that far, so this will do for now.

Still working on the tune.  But on only 6-7psi it's surprisingly quick.   Still babying it though trying too keep the stock th350 alive long enough to get the rest of the parts to swap the 4l80e in.

Also put the 67 on the chassis dyno they had there.  Was 87* out that day and having the car running in the middle of a blacktop parking lot didn't help matters.   Was seeing 140* intake air temps which was making the computer pull 10 degrees of timing (down to 16 instead of 26 degrees total timing).  Still made 304hp at the tires.
