olds307 and 403
- Oct 14, 2008
It is a very wide rad, the Champion 4 core. So is the Cold Case rad with 2, 1.25" cores. Pagrunt had to modify quite a few things to fit it. I am planning on the A body version of Cold Case or the Autocity version with 2, 1 1/8" cores for my 70S when I put in the 424 403 stroker.Their 4 row looks promising but the tanks are 3/4” thicker and I haven’t measured to see if it would fit without issue. I’ll like swap thermostats first thing just to note the difference before buying anything else. And then likely the 1” tube 2 row.
