Crankshafts! L98 vs LT1?
I'm shoping for a new crank to rebuild my 1995 LT1 engine to 383. I find there is very little advertised specifically for the LT1. I was beginning to assume that 87 & up L98's and LT1's used the same crank but today I came across several cranks of 3.75 stroke and 1 pc rear seal which stated (Not for LT1). Are there differences in the snout? Are the cranks generally interchangeable with a few "exceptions"? What should I be looking for to determine if a crank is suitable for an LT1?

If you're building from scratch, there should be no difference. The stroker crank I use is not LT1 specific. I even changed the rotating ***'y to full neutral balance when building my current shortblock. The snouts are all the same and even the stock LT1 crank has a provision for a keyed hub, it's just not used with the factory damper set-up.

I am doing the same with my 95. I just bought an Eagle crank from CNC-Motorsports. Go to their site and look up Eagle crankshaft # 10352375057E. It is a 3.75 stroke crank listed for the Lt1.
I bought a complete stroker kit from these people a couple of years ago, and was happy with their service.
