Default Lq9 crank

Hey guys I wanted to see what you guys thought about this.. A while back I bought an 05 lq9 and striped it completely and sold everything except the block with the intentions of getting a full 408 rotating assembly and boosting it, well like many people budgets and plans change, so now I want to put a stock crank and forge the rest.... So here's my question, what kind of crank can I put back in it because Im understanding that weight was different and the back of the crank on the trucks were longer or something, I really wish I wouldn't have sold it but here I am in this situation, so any help is appreciated, thanks guys

The early 6.0's had the longer crank, in the rear. I think it was the first year or maybe two that they were in the trucks. After that they are the same as all other LS engines.

My car is a 99 and I can't remember if it has a 24 or 58... And as for the "earlier" 6.0's does that include 05's?

Nope, we are talking like the first two years of them. Your 99 car will be a 24X motor and that 05 may be 58X.
