My 273 Experiment

... a 318-3 truck crank is way,way way overkill in a 273. did you know those cranks are good for 8000 rpm (what I have heard). they are heavy and I am not sure but I think they have a different flange on the end. But if you've got one....I guess you could use it. Just a cast 318 crank would be just fine or a steel crank from a 67 318. Even a 318 poly crank would work (they are steel, most of them) the cast crank would be lighter...
