Hey Pharoah thanks for the informative reply. I'm well aware of how newbs are perceived regardless of whether or not they've been on other boards before With that said, different boards organize and use different descriptions of topics, making it difficult to always know the right search terms. But I'll do my best.
I'm not necessarily set on the Tokico's, but they seemed like a step up from OEM replacement with a little bit of lowering, which sounds perfect to me. I enjoy a spirited drive as much as the next guy, but I don't need a car that I can't drive on the street comfortably. Plus the whole "all-in-one" kit has its appeal. If there's other setups that would fit this description, I'm all ears (as well as searching myself). I don't mind buying shocks/springs separately as long as I get good results in a reasonable timeframe.
Boy, do I know about things not being happy bolt on, rainbows, butterflies, and reach-arounds. There's always work involved.
I know the new engine runs and drives - it's still in the pickup (CK, not S10). I figure on transferring over all the ecm and associated wiring. Most of the Z wiring I'm assuming will be taken out. The trans was purchased separately, but is in good condition, and will get new fluid and gasket before it goes in.
The only reason to do the suspension and bushings now is that it's easier to get to all the bushings without the motor (and weight) in there.
It already had a TH350 in it from the previous previous owner, so I'd assume the smaller-housing 200r4 will fit without too much hassle. As I mentioned in my initial post, I found a deal on another JTR kit, and that included a flange for the differential that makes the driveshaft 100% Chevy, albeit shortened. A coworker is giving me a driveshaft that he was about to throw out since it was taking up space. Hopefully the yoke is the same (should be). Just have to get that measured, shortened, and balanced.
I do remember reading that that Subaru rear diff was a good swap. If I ever decide to get more power out of the v6, I'll give the diff some thought, but I'm not worried about it for now.
As far as the fuel system, I know I'll need an electric fuel pump. Are the stock lines sufficient?
Thanks for your help and patience. I'll keep on that search button.
Here's a few pics as I purchased it, and the engine bay after a quick refresh in satin black. It ain't the prettiest, but it'll hold the motor just fine.
