305 crank in 350
Hi,
I just wanted to know if I could use my 305 crank into a 350 block I have. I'm kind of in a bind cause I don't have a one piece crank for my 350. I figured the 86 305 crank would be fine because a 305 is just a small bore 350, still with the same stroke. what do you think?

When you have all the parts together, get the rotating assembly balanced.
Might be cheaper to buy a new 350 crank.

The 305 and 350 have the same crank, they only differ in the balancing. As five7kid said it is probably cheaper to just buy a new crank; then have that one machined and balanced. New cranks are cheap these days.
