Buying a crank from ebay, help.

ok I have a 350 chevy in the garage. The guy I got it from said it was a roller motor. its a two bolt with these casting #'s 14093638. Im looking at a 383 crank on ebay, but im not sur if it is right. Roller motoers came out in 1987 right? I know this engine uses a one peice rear main seal, but the ebay advertisement stats that the crank "is for a one peice rear main seal 1989-98 roller motors." Mine is a roller but not a 89-98. Whats up with that?? can I use the crank? is the advertisment wrong? What is the difference between the gen I, II, and III 350's and what gen is mine? I dont want to blow 300$ please advise.

Yes you can use the crank, you have a gen I roller, Gen II is lt1(you can still genII bottom end parts i believe) get III is the ls1. The ad must be wrong.

The actual "roller" part has nothing to do with the crankshaft. All you need to know is whether it is a 1 or 2 pc rear main seal (along with the obvious things like mains and stroke).

Yes, any 1 pc rear seal crank will interchange, meaning, the LTx cranks can be stuffed into a Gen. I block, seal depending.
