Default '77 Radiator Question

Is the stock radiator from a '77 a 3 row? It is an AC car if that makes a difference.

Thanks,
Adam

My 77, L48, automatic had a 3 row from the factory. I upgraded to an L82 style stock replacement, which is a 4 row. My car had factory air originally.

Hey BK - Nice - I wasn't aware that the L82 had a 4 core. I'll look into that.

Thanks,
Adam

Must be because the L82 likely had the TH400. Those were heavier, stronger, but I believe they had more friction / drag. Therefore, more heat?

I originally bought a generic replacement radiator which was a 3 row and I had overheating problems - with all the seals, shroud etc in place. I changed to the same generic brand 4 row, specd as an L82 replacement, with auto trans and AC, and the problems disappeared.
