Someone please clarify something for me. I know that the 305 and 350 cranks have the same stroke, but they are DIFFERENT cranks, right?? Can I use a 305 crank in a 350 build? How can I tell one from the other in a junk yard??

anyone??

Yes the strokes are the same but....the couter weights are different from what I have heard. So No the cranks are not the same.
as far as determining in a junk yard...Dont bother. I Highly reccomend if you are going to get a stock crank redone go to your local machine and ask them. I have heard tons of stories about how junkyard selling people 305s when they were told they were 350 engines. You might become in the same situation with crankshafts. BTW You might want to look into a scat/eagle crank, by the same price tag you get it run ready you could have bought a new crank.

The cranks are visibly the same, but the counter weights are balanced for the much smaller and lighter 305 pistons. The only way you can use a 305 crank in a 350 is to buy the nice light race pistons. And as always with a high performance engine have your machine shop balance the rotating assy. And yes the aftermarket cranks are such a great deal these days its hard to justify machining a stock crank. Jeff

From what I know, it's the same crank. The 305 pistons aren't really lighter. The only thing I'd recommend is before actually building the engine to get the rotating assembly balanced. It's the only way to properly build an engine. I think the cranks are the same, besides the one piece or two piece rear seal thing. But that one is a year thing.
