I am in the process of doing a 6cy to V8 swap in my 67. I picked up a 351w that has the serpentine setup. I am going to change back to the v-belt style pulley because I did the F-100 steering conversion and I am going with the radiator that is notched out for it. My biggest question is I have a 4 bolt balancer and was told I need to switch to a 3 bolt. I'm not an engine guy, can anyone tell me the reasoning for this?
