Differences b/w 305 and 350 crank
Guys,
What are the differences between a 305 crank and a 350 crank? I've heard that the journals and stroke are the same but balancing may be different. Is anyone running a 305 crank in a 350 and have you had any problems?
Thanks,
Dave

They are both identical, except after balancing. The 350 crank is balanced with less material removal, plus the counter weights grooves are offset (can't lay a straight edge flat on them). The 305 crank is balanced with more material removal, plus the counter weights grooves are not offset (you can lay a straight edge flat on them). Other than that, they share the same part number (prior to balancing).
