one piece 305 crank (same stroke as 350 3.48") in a 350 one peice block do they have the same counterweights or what not???

 

it has a little different balancec to it since the 350s pistons are bigger.

Tas is correct they have the same stroke but are balanced differently. a guy i know is running one in his but personally i would not do it.

Not worth the balance job when a new crank isn't all that much.

 

the cranks are different, the counterweights are different, and yes the balance issue has already been brought up,it can be done but for any other reason than just be different it wouldnt be worth it
