Weasil Posted October 22, 2022 Report Share Posted October 22, 2022 I need to find a Gen3 5.3 aluminum block. Some place close to the Chicago area would be nice. I dropped a valve and broke a cylinder wall. Quote Link to comment Share on other sites More sharing options...
Wheelman_99 - C Rallo Posted October 23, 2022 Report Share Posted October 23, 2022 Have you checked car-part.com? Look at small GM SUV's with 5.3. Trail Blazer for example. LM4 in the earlier ones, then L33 as you likely know. Quote Link to comment Share on other sites More sharing options...
Weasil Posted October 23, 2022 Author Report Share Posted October 23, 2022 Was first place I looked at. They want to sell complete motor Quote Link to comment Share on other sites More sharing options...
Wheelman_99 - C Rallo Posted October 24, 2022 Report Share Posted October 24, 2022 Figured you might need other parts along the way. Are you on Facebook? There are tons of groups dedicated to "LS" engines and related parts Quote Link to comment Share on other sites More sharing options...
obscene Posted October 24, 2022 Report Share Posted October 24, 2022 weren't all the truck engines an iron block though? i think you need corvette or camaro versions for aluminum. 1 Quote Link to comment Share on other sites More sharing options...
Wheelman_99 - C Rallo Posted October 24, 2022 Report Share Posted October 24, 2022 (edited) The small SUV's (including the Subaru(I meant Saab) and Isuzu) had Alum blocks, as did the H3 and the Colorado/Canyon on the same platform, though the latter is a gen4 block.

I was definitely confused, I'd seen rumor of subie/LS swaps, but couldn't think of any that came that way. Started making a joke about "similar construction" though... 1 1 Quote Link to comment Share on other sites More sharing options...

Sounds familiar. Maybe just the 4x4 ones? It was to keep payload/towing up. Quote Link to comment Share on other sites More sharing options...

It was to keep payload/towing up. I believe the 4x4 model are more likely to have aluminum block engine. It was for weight savings for payload.
