I'm sure there is a bunch of threads on this already. I did the 3G swap in my 87 f150 and I want to do it in my 89 f250 with the 7.3 IDI. I understand the basics (wiring, mounting, etc)
What i want to find out is what alternator will I need? Can I find it on any vehicles in the JY? Will the pulley (double v-belt) need to be changed?
