I was going to run an ac comp on mine but the power steering belt kept slipping on runs going slow so I went electric instead, if you go any farther out on the crankshaft the snout of the crank may break off trying to get it's own pully,I broke the end off of a 429 ford once doing that, a sammie I would think would have an even smaller crankshaft, I would do the maintenance on the rig befor I left for the trails and leave that heavy comp at home.
