Guys:
I'm not sure but my radiator may be a Griffin. It is the one that came from Contemporary in 1991. I'll check when I get home this weekend and let you know what I find. I'm swapping to new Edlebrock heads (the 72 cc versions) this weekend to get my compression ratio up to a respectable number for my Webers. Wish me luck. It coulod end almost two years of frustrations.
