Crankshaft replacement

[James Bell]

I need to replace my crankshaft in my Gen-1. I was told that a Gen-2 crank would fit in a Gen-1 block. Dimensionally the Gen-2 crank is the same, except for the crank sensor wheel. The sensor ends up in the same place, but has a different shape to it. Arrow told me that they use Gen-2 cranks in Gen-1 blocks on some rebuilds because the early cranks are unavailable. Has anyone ever herd of the cranks being interchangeable?

I'm not sure if they are interchangeable, but here is one off a '97 GTS for sale.

Thank you for the lead Jim, but I was looking to install a stroker crank. Moldex Machining makes two different size strokes for a Gen-2 crankshaft. They were just not sure about it fitting in a Gen-1. The only difference that stood out was the crank signal wheel. All the bearing journals were the same.

Has anyone seen the two cranks side by side? I have only seen pictures of the Gen-2 crank, but it looks the same as the early model. My only concern is the crank trigger wheel reaching the pick-up. Getting a measurement of the diameter of the sensor wheel should help.
