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.

You got to get one with the SAAB plastic cover!

I forgot about that... Sounds familiar. Maybe just the 4x4 ones? 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.
