Spent the weekend working on the Suzuki, and managed to get a few things figured out. First of all, I was finally able to ID the engine: it looks to be an Isuzu 1.4 SOHC that's mated to a T5 transmission. I'm guessing the engine/tranny combo was pulled from an early Chevette, since that was the stock config for that car. Someone wrote "no oil" on the camshaft cover, which is pretty much a dead giveaway that this was a junkyard motor. The T5 is a crazy long transmission, which is why the engine is pushed so far forward that there's no room for a clutch fan. The transfer case appears to be in its stock position, though, which is good because that means the driveshaft lengths haven't been messed with. One of the front u-joints has failed, though. Hope I can find a replacement!
Also: in order to clear the front pumpkin, whoever did the swap simply bashed in the oil pan with a hammer. It looks pretty bad, but doesn't seem to leak.
I also gutted the interior and removed the sound deadening, which had failed and was flaking off. I'll need to patch 5 spots where there's rust-through, but overall not bad. My plan is to get that done, then prime and respray the interior, and then lay down some Noico or the like. Already on the lookout for a replacement carpet kit.
Pulled the fender flares off, half expecting to see a bunch of rust holes. To my surprise, they were perfectly solid - just a bit of surface rust. I also gave the rig a quick hand polish, and the paint came right back. A quick machine buff will really put the shine back into it. I love the red oxide primer that's peeking through in spots!
Overall, the plan for this rig is:
1) Get the interior sorted and looking good (carpet, upholstery, headliner)
2) Sort out the electrical (has no fuel or temp gauge)
3) Baseline fluids
Going to leave the exterior as is, picking away at the body rust. I love the patina and will try to preserve it. I'll post occasional pics here as I make progress.
