Lsa crankshaft
Lsa crankshaft From my research it's a 3.62 forged steel crank shaft. Would it be a drop in on a ls2? For 485 bucks it's a hell of a budget crank. Anyone know if it's a 58x or if it's got the stock ls2 size snout ? What about flywheel bolt configuration?

Nope!
ZR1 is unique with a 9 bolt crank flange.
LSA is unique with 8 bolt crank flange.

I'm curious for the same reason as the op. Its a "forged steel" crankshaft. And for a hell of a price at that. For the stock cube or 370 guys etc. That seems like a helluva deal. Added protection at a fraction of the cost. If it'll work.
I'm def not educated on the different motors But is the lsa a dry sump setup? If not then it should be the same length as our cranks?????
Am I completley out of line here?

Why would they make cranks with 2 different bolt patterns??
This isn't the answer but it clears some things up.

12603616 614 at my local dealer,590 on parts direct.Still not sure on alloy wonder if it is 5140? still a good price. Look out compstar,here we come...finally what appears to be an affordable decent 3.622 crank.Yes I know it has an 8 bolt flange,but that seems to be the direction the general is headed and most of us would be upgrading the flywheel or flexplate anyways.
I'm sure someone would make a flexplate with that bolt pattern. Depending on the price of it though it may just be cheaper to buy a crank that will work with the pattern we're used to.
EDIT: Anyone have a price on the LS9 crank or part number?

does gm not make a flexplate for the lsa? i know you have the option of getting a ctsv with auto? i dont see why you could not use a auto ctsv flexplate?
That is a good point. There would be your 8 bolt flexplate. It is a stock one though, but again on the budget it may not be a bad option. I'd like to see some people track down these part numbers.
