Quote: There was an '84 Ram with black booster and 2 bolt MC. My understanding is, even with the smaller booster, with (non-factory) tall valve covers you may have to relocate everything up to an inch further away from the engine???
Black booster? For a 440 you just need to swap in a 3/4 ton booster of the same era truck. All 3/4 tons use the small diameter booster which in the 70s was the same used for 440 trucks. the 383/400 B-Blocks can use the big diameter but tall valve covers may be an issue
