You'll hpefully forgive me for being a bit snippy, but!

I'm always spun around by guys who will spend heavy money on electric water pumps and fans and won't replace the radiator till disaster befalls them, or rather the engine that's attached to the old radiator.

A basic rule of thumb is, or should be, that every "new" motor gets all new coolant hoses and radiator. Do the heater core while your there. This should be first in your rebuild estimate for the simple reason is simply when these things let go, the likely hood of ruining your expensive hot rod motor is really, Really, REALLY high. The cost of this kind of a disaster doesn't offset the puny power gains that can be had with electric pumps and fans especially for a street driven engine.
