Generation IV Internal Engine - 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

what type of vehicle and computer are you installing it in. reason 24 tooth or 58 tooth.

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?
