Re: My 73 Chevelle turbo LS swap
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

Re: My 73 Chevelle turbo LS swap
Looks like I need to go back and update the old posts with pics again now that photof**kup killed all the pics......
Yes, its about 3/4" below the crossmember. If i had to do it again i would have used the Holley pan.

Re: My 73 Chevelle turbo LS swap
What's the brand of your new wheels? Are they forged?

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

Re: My 73 Chevelle turbo LS swap
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.

Got a shifter for it

Got my brother to mount the tires for me (haven't put them on the car yet)


Also got a deal on a 4l80e trans

Re: My 73 Chevelle turbo LS swap
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.

Re: My 73 Chevelle turbo LS swap
Some pics from a show at my dad's work, Took both the 73 and the 67.

Re: My 73 Chevelle turbo LS swap
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.
