from my perspective the generator is more reliable, 3 of my old cars have generators the chevy has alternator , in 35 years 3 chevy alternator failures, no generator failures

I think you can either get kits or separate pulleys that have the same OD so the speed will not be effected. Hard to beat a delco alternator for reliability.
They do look ugly on a flathead imho.
