I just bought a 53 6400 dually flatbed w/hoist for use as a work truck and want to beef it up. I have to choose between two available engines, either a smallblock Chevy 350 or an Olds Rocket 88 (not sure what size, but it looks bigger than the 350). Any advice on which would make a more powerful engine for this truck? Everything I find says they were very similar engines, so how can I know which one will deliver the most HP?
