s10 AD swap, why not 4x4 and why not 2nd gen?

[jhnpldng]

Been reading over all the S10 to AD frame swap threads here and what I can find elsewhere. The only downside I've read about using a 4wd frame is that the torsion bars get in the way. In the way of what? They don't get in the way on the S10s and it's a complete frame swap so they would just go right along with it. Is it just that they're not friendly for bagging/slamming? The rear axle would already be the preferred width. The truck wouldn't look 4wd with no locking hubs. The transfer case shifter would have to be dealt with but I don't think it would be a big deal. We have hills, mud and occasional snow and ice here so it would be pretty handy and could still be lower than the stock AD.

Next is the 2nd gen S10s. Has anyone done one of those? I'd have to bring the harness and ecm/pcm over but that doesn't bother me. I've done that sort of thing before.

I just bought 4 ADs, two with titles, and already have a 85 S10 ext cab 4x4 so I was thinking of reusing the frame/engine/tranny for the first AD and keeping it as a long bed. The downside is that the S10 is a 2.8 but it runs great and has a good 700R4.

For the second one, I'd like to have the 4.3 vortec in it but not too many 1st gen S10s had them. Lots of blazers did but the wheel base is wrong on those but then again, a 4 door blazer is 107" and short bed AD is 112. Then again, the stock ADs already look like the axle's too far forward so.... I don't know. Not sure what other issues the blazers have for the swap. I know most people don't like the CPI but I like them. The spider injectors are pretty cheap as rebuilts from rockauto but half the time the problem is the fuel pressure regulator and that can be gotten separate now for 30 bucks. I had a 4.3 cpi in a 63 gmc and it looked like it belonged in there due to the plenum almost matching the bump in the firewall.
I suppose I could find a 1st gen S10 long bed with 4.3 tbi, 1st gen blazer with 4.3 cpi and do double swapping but that's a lot of work. Either that or just wait til I find a 1st gen pickup that has the cpi.

So does anyone have any experience with the S10 swap that's not strictly 2wd 1st gen?
