its physically possible, but I doubt the motor would last long. THe counter weights are different on those two cranks.

I built a 350 for my old truck using a 305 crank. I had no problems, BUT, knowing what I know now and having seen the bobweight differences first hand, I'd wouldn't recommend doing it without balancing it. (It would need heavy metal and the cost would prolly negate any savings using a 305 crank instead of the 350 crank).

i will problably just get a 350 crank then becuase i wanted to toss a mild cam and intake in it. dont want to take the chance of screwin it up. its hard to find engine parts in utah. not like it is in michigan. took me a year to find a 350 block. no junk yards hard one and people selling them wanted too much for a short block. finally picked up the block and heads for $50 came with 16 pistons and rods guess i can pick and choose.

I've known builders to use 305 cranks with ultra light piston and rods. But the price of those negate the savings agian.
