Young friend of mine is rebuilding a Chevy 350 and he needs a crank. I have a 305 crank in the shop I will never use. I'd be happy to give it to him if it will work. I know that both engines have the same stroke and journal size and that, from a physical standpoint, they will interchange. What I want to know is if there are any other differences, such as balance, that must be addressed when swapping cranks from one to the other. I don't want to give my friend an unnecessarily expensive solution to his problem.
Same crank no balance difference.
According to my "Chevy V8 Casting numbers 1955-93" the 76-85 305 used crankshaft #3932442.
Some 68-81 passenger cars and 69-85 trucks are also listed as using the # 3932442.
Check your casting number.
