First of all I want to thank "512Stroker" for sharing your experience . I learned a lot . I am experiencing the same issues with my 383 scamp . After 5 minutes of running the temps go to 220-230 . these engines were never intended to operate at these temps and I don't want to cook my motor . I am thinking that my oem radiator doesn't have enough volume to cool properly . so I went on a search . Every vendor wants to sell you a radiator but won't give out the overall dimentions . Or don't know what they are or …. I am of the opinion that (2) 1 1/4 or (2) 1 1/2" cores will do the trick . The question of bolting it in is the big issue . I'M not hacking up my finished car just to get a rad to fit . Again , thanks 512Stroker
