Does anyone have a list of what blocks, aside from the LS's, are aluminum?

I think the only other one is the 53.L / L33 ?.. but that information may be dated...

I think the code for them is L92 but all of the new 6.2's in trucks are aluminum (basiclly a LS3 block), and I am pretty sure the G8/automatic 5th gen Camaro had the L76 (6.0 with L92 heads). And like bczee said there is the L33 5.3.

Trailblazers and GMC Envoys use the all-aluminum 5.3 LH6.

Lm4 which is the standard 5.3 that came in trailblazers are also aluminum block everything was the same as the lm7 just lighter. If you go on wikipedia they have a pretty complete description of the engines

Great info. I didn't see anything aluminum for the L98 and L99 though.

The L98 is harder to find information on, because of the Gen I(SBC) that uses the same RPO. Somewhere or another I found information on it that said it was aluminum block, and noted it down in my file, but I can't find the online source now... I'll see if I can't find it again.

EDIT: Yeah... still can't find anything that specifically says the L98 is aluminum block. However, many articles suggest that it's just a variant of the L76, which IS aluminum block.

Makes sense, GM does have a habit of reusing codes. Thanks for list, should help more than a handful of people that want to save a few pounds in the front w/o going LS1/2.

FWIW, I thought the 5th Gen auto camaro was a 6.2 (L99) The auto G8 is a 6.0 (L76).
