ls crank the same as gsr crank?

i have a problem. i am trying to build up a gsr block that i have, but i need a crankshaft. i have two ls,(90-93 b18a1) blocks with cranks, and was wondering if i could use the crank out of one of those for the gsr block. thanks

i'm not sure but why don't you try finding a website that sells engine parts and look up the two different cranks and see if they are the same part number? might be worth a shot.

nodbody has ever tried putting an ls crank into a gsr block?
