I'm still new to the LS based engines and I had a few questions ! Can I use a LS2,Lq4/9 crank in a LS1 block ? If so, will I benefit from it ? I know they have a longer stroke but don't know if I can just drop it in. Sorry for the newb questions but how else will I find the info that I need ! Thanks in advance !

The LS2 and LQ4 both have a 3.622 stroke like the LS1. The increase in cubic inches is due to the larger bore, 4.0" vs. 3.898". Depending on the casting number on the crank, may be able to use it in an LS1 block. Here's a good article the articulates the differences between the crankshafts. Apparently, the 6.0L crank is about a pound heavier than the 5.7L crank.
