This makes me want to Turbo my swap which didnt even make it to my car yet. what truck headers would you use if i were to use factory headers. I was told its popular to use escalade headers and flip them up so they face forward and start routing the turbo. im swapping a LS1 in a 86' 635CSI. my main issue will be clearance with the steering box...im trying to as little fabrication as possible and would rather use some type of hugger header if i dont do the turbo so i would clear the Steering box.
any help would be greatly appreciated

The headers I used came with my motor, an 07 LQ4 out of a Chevy Express van.

C6Antwon,
Glad to see you got this bad boy running. I wanted to thank you again for the braided hose assembly link. Its exactly what I needed. If you don't mind one more question.. how did you cut your black hose?
thanks in advance!

Went to a track rental today. I found out that the car has an open diff (FUUUUU), time for an LSD. All passes were on 6psi (488whp). My first 60' of the day was 1.85, but the car shifted weird into 3rd so I let out and went 12.2 @ 87mph LOL. Second pass was the fastest and here it is:
Im going to try and put some weight in the trunk and get the 60' down. If the car would 1.7 60' I think it would 10's. O well, time for a limited slip and some weight!
