Radiator for blown 440 in Duster

Putting together a blower motor for the Duster. Space is tight as it is between engine and radiator and the blower drive is only going to make things worse. Wondering what folks are using for radiator (and fan) on a setup like this. Would a two row aluminum rad keep temps under control? Until now I've had a 22" 3-row copper/brass which as been adequate with the NA 440.

It'd be nice if an inexpensive Champion radiator would work.


where i can find the crakshaft drive belt pulley ?
