Default whats the difference between l92 and ls2 blocks?

i searched around the forums and i couldnt find a definite answer to this but whats the difference between the l92 motor vs ls2? i see alot of people go with the ls2/l92/l76 combo, why not just get a l92 longblock with a l76 intake? is there flaws in the l92 block. and is a l92 just a stroked ls2?

trying to decide which block/head combo would be best to start off with, my goal would be 500-600ish whp n/a daily driven, and if there are major difference between them for hp wise.

The L92 uses the same stroke as the LS1, LS2, LS3, LQ9, etc at 3.62. The difference is the bore is 4.060" instead of 4.00" on the LS2. There are some other structural differences too.

I was wondering the same thing. Why would you go with an LS2 or LQ9 block over an L92 block?

Cheaper and easier to find in a junkyard. I got a LQ9 block for a little bit over $200.
