Setrab Oil Cooler - Huge (50-172-4063, AN-12)

I bought this years ago at a NASCAR used parts store. I believe it is the same core as the Setrab 50-172-7612 by uses permanently mounted AN-12 fittings instead of the newer M22 female arrangement. It is about 7"x2"x22", truly huge. Setrab rates the 50-172-7612 at 600+ horse power (and gets $600 for it).

I bought this originally for my 4ktq when I was considering going crazy with it. I ended up with a much smaller Setrab instead.

I am looking for $150 for it.
