have 37 with 350 and ran it for years on the original radiator with a 13" pusher fan as extra. Ran good but would "heat up" in parades.
I have a 52 panel with 305 and have a 4 core orignal style radiator in it and its ran cool sitting idling in the shop for long periods.
There has been mamy threads on here about radiators and the upward cost of them....how ever I've noticed several guys have found good bargains, even with Aluminum, if you check around.
Several here on the bolt have done it. Good luck.
