I am swapping out a 305 for a 350 2-bolt main in an '84 Z28, and believe that the 305 and 350 have the same stroke. All I have is the 350 block so am I able to use the crankshaft & connecting rods from the 305 in the 350?

Thank you.
Kevin

 

the 305 & 350 cranks start out the same at the factory,but 305 crank will have more weight drilled out in order to properly balance the lighter 305 pistons-so balance will be way off using stock-ish 350 pistons...
