remember that the 283 is a short stroke engine & the 350 a long stroke. that means that to get any performance from the 283 the truck needs to be geared deeper than it would be for a 350. so that being said there may not be any economy fuel wise to be gained with a short stroke engine. also trying to o/d short stroke engines causes the power enrichment system in the carb to think it is climbing a hill so it opens due to lower vacuum & there goes more fuel. like was said before, it is all in what you want. the engine, trans & rear axle are all a system that needs to be properly matched. now, 350s have their place, but i luv 283s! power pack heads, rochester 4-jet carb, 350 hp hyd cam, 4spd t10, 3.73 posi & let it wind!
