- - blocks (https://ls1tech.com/forums/generation-iii-external-engine/1104773-blocks.html)

Does anyone have a list of sticky where it gives a list of what types of blocks come from which gm cars? (I.e. 6.0 iron blocks, lq9, etc.) Or can anyone give type up that for me? Thanks.

What is it specifically that you are looking for (which block or engine)? Here is the most popular list of engines and the (US) platforms they were used on.

LR4, 4.8L = 1500 Trucks (1999-2006?)
LM7, 5.3L = 1500 Trucks, SUVs, Vans (1999-2006?)
LS1, 5.7L = Corvette (1997-2004), Camaro, GTO (2004)
LS6, 5.7L = Corvette (2001-2004), CTS-V (2003?-2004)
LQ4, 6.0L = 1500HD, 2500, 2500HD Trucks, Vans and Suburbans
LQ9, 6.0L = Silverado SS, Denali, Escalade
LS2, 6.0L = Corvette (2005-2007), GTO (205-2006), Trailblazer SS, CTS-V (2004-2007)

i was thinking of the 6.0 ones. truck ones are iron and the ls2's arent correct?

correct the ls2 is aluminum and the truck motors are iron

would a 2004 escalade have a 6.0 iron block in it? whats the difference between the lq4 and lq9?
