Should be good. Small Block Chevy needs no introduction, anywhere on earth. Transmission'll be in the Turbo Hydramatic series (THM). Probably THM400, maybe THM350. Same characteristics as the Fords of that era, three speeds, no OK, no converter lockup.
Get that many miles and years, engine "accessories" like fuel and water pump, starter, alternator, become expendable maintenance items. When we had the '83 Ford, I carried a few spare parts: Starter, Solenoid, Alternator, Voltage Regulator, Ignition Coil, Ignition Module. Over the years, I replaced Starter and Alternator twice each, Regulator twice, Coil once. Module got so hot for so long, the epoxy "potting" melted and ran down the fender liner. Still ran fine, but I replaced it and cleaned/painted the area before I put the coach up for sale.
I think the 350 has a mechanical engine mounted fuel pump. Watch out for its condition, keep good filters in the system, watch for pinholes in any rubber hoses. Vapor lock is possible with this system. Should be a tiny fuel filter in the carburetor inlet. Replace it CAREFULLY then install an in-line filter before it. Never go back in there again. It's so small, it's an engine-stopper. And, the fine threads that retain the filter are easy to strip.
