That's a nice swap man, I'm driving a rental 2012 Tahoe with 16k miles and a 5.3 while my 1999 tahoe gets body work done w...I really want to get one of these and to put in my regal now.

the radiator hoses are stock ones for a 01 suburban that I just trimmed off a bit. No air yet, I planned on making a bracket that goes where the belt tensioner is and use a R4 compressor for a 90 chevy pickup. the A/C hoses I plan to use are for a 85 cutlass with a 307 olds. we will see how they work.

Very clean swap, I was looking at your pics in your profile earlier. With those iroc wheels, did you use just fronts or just rears or what? I always wondered because the fronts and rears have a different offset as a set.
1979 Olds Cutlass. Tuned LT1, 1.6 rocker arms. TH350 . Locked 7.5 rear.
1994 Lincoln Town Car, 100% stock.
1999 Jeep Cherokee, 4.0, 4X4. Stock for now.

I think my AC pump was a '91 Caprice, or Camaro I don't remember. The bracket was kinda tricky, but it's always fun making your own stuff

that compressor bracket and mounting looks awesome, that is exacty how it looks in my head! My wheels are irocs off the 88-90 models. They are regular front and backs, I put the front on the back and the backs on the front with 1/2" spacers and longer studs. Thanks everyone on the positive coments, I am happy with the way it is going now!

i looked at the modified crossmember and it's different then mine, But i had a 2004r, now i'm going with a 4l65E. Went with the same idea of extending the trans mount pad. 8)

how much power does that 5.3l make might want to go that route because the motors are dirt cheap instead of an ls1
