I know this have been covered many times. I've used the search and read a lot of threads about how to tell the difference but the crankshaft I'm about to buy has markings I didn't see in other threads about. The seller told me this is off his b18c1 I just want to make sure before I buy it. Please help. Thank you.

Thank you for all the response but I've read all those threads already. I still can't find one that's matching the numbers on the crankshaft. I see the 7 on the crank.

I would say also, it's GSR/P72-crank (number 7, shape of counterweights).

I have a buddy's gsr crankshaft I compared it to and the casting numbers are different. Why is there a C3 instead of a C4 next to the 7 on the counterweight?

Bump. Anyone else have any input ? After viewing the pictures I attached

Those are codes, because of diameter tolerances. Number indicate main journal size and letter is for rod journal. So understandably, these varied between different cranks.
