Re: 71 GMC turbo LS build

Also, Finished painting the frame while I had the bed off. When I had everything done out back, I mounted up my radiator and intercooler.

Radiator: universal 31x19 double pass (same side inlet/outlet for LS) $115 on Ebay
Intercooler: Stock 1999-2003 7.3 powerstroke (perfect size, and had one laying around the shop)

Used a 4" hole saw and cut holes in the core support. Some additional trimming on the back side of the core support was necessary as you can see in the pictures, but thats no big deal. I utilized the top two mounts on the IC, and the on the bottom I mounted rubber pads on the frame. IC is mounted super stout.

the radiator fits perfectly between the intercooler Inlet/outlet. I had to relocate the stock lower radiator mounts, and the upper radiator mounts by moving them in towards each other by 1 hole, and drilling an additional hole. some minor trimming and clearancing was done on the bottom of the core support to clear the thicker core radiator, but I think it was mostly because my core support isnt the straightest.




not sure how to get my pictures to rotate, so sorry for the sideways pics!

You guys cant tell me that intercooler doesn't look bad ass! Only downside so far, is the intercooler is so big, the factory hood latch will not fit, I have an Idea to solve that problem, but do you guys have any suggestions (and Im not wanting hood pins!)
