65 Chevy 283 exhaust manifolds on a 400?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Engine front end parts from different years do not mix well. Unless the PS pump and mounting brackets came on either the 400 or the 283 you have now, get the complete setup off of one engine. This means ALL the pulleys.

Btw, it's not that big a deal to run a passenger side alternator. You do have to pay attention to the wiring, but the early and later style alternators, at least through the SI type (mid 80s or so) will physically interchange on the mountings.
