I replaced my stock recored radiator with a Afco brand aluminum one in my '37. Since I am running a 250 cubic engine, I modified the mounts to fit my application. Mine is mounted way low and forward of a stock location. With that being said, the fit and finish was first rate in my opinion. The only difference from stock was the outlets pointing straight out where as the stock units point towards the motor so the hoses are straight. The core is thicker as are the tanks, so if clearance is a issue, be warned. So far I am really happy with it (been in a year or more), it came with a 18 psi radiator cap, but I run a 14 just for good measure. Not once has ever gone over thermostat temp.
My old radiator was recored and cooled just fine. The problem was the old tanks were so thin, each time it heated up the top tank would flex and over time the solder joint would crack. I was at the point of once a year pulling it out for repair, and the rest of the year, wiping small drops of coolant off the engine and firewall.
