360 Serpentine conversion - March Performance vs CVF Racing

You can get performance ratio pulleys in a V belt configuration. FWIW....

The have the March pulley set up on my E-Cuda. There very old. Only paid like $250 with the PS pulley & all the brackets. Prices aside, what your really looking at is pulley diameter. There looks aside, that’s what there used for. Slowing down the water pump. There is a few HP in this. At your level, it’s probably 5-10hp.

I made the change because my OE pulleies were bent and I was throwing belts at a low 4500 rpm. At the time, I spent less on the March serpentine pulley set up then resto OE pullies.
