Hey guys I have inherited a 1973 chevy k20 camper special. My question is what would be the best transmission to use for a swap it has a built 350 turbo 3 speed automatic and 430 gears in the rear. I'm looking to just make it more fuel efficient for towing. The engine is stock with a slight rv cam. Only changes are carb swap to a holler 600 cfm. 65 mph= 3500 rpm roughly 6 mile to the gallon. Not to good on the wallet
