The 97 is a balance shaft with non adjustable rocker arms. The 88 is a non balance shaft with adjustable rockers. I do believe the 88 did have the roller cam, tho.
GM made so many variations of the 4.3 that the only way to find out is to try it. I think if you use the rocker arms off the 88 and the matching push rods it might just work. Not sure if the rocker arm studs will let you do that.
Do some research on putting a hotter cam in a 96 up 4.3. Some of the cam manufacturers explain what has to be done to put adjustable rocker arms on the 96+ engines.
Unless that 88 engine is really fresh or some other good reason to use it 96+ 4.3's are easy to find and run around $350 for a decent used one. Buy the time you buy intake and head gaskets and bolts you'll be half way there anyway. 96+ head bolts aren't reusable.
I just pulled a 4.3 out of my 99 with only 125K on it to put in a LQ9 6.0. You can have that one for the going rate. If you're in the Chicago area. Otherwise you can find one locally I'm sure.
Not listing my engine as a for sale item. Just mentioned it in passing as an example of whats out there.

Also have a 1998 S10 2.2 that I want to swap engine and transmission with the Jimmy.
Jimmy is a great donor and runs perfect. Anyone done this?
Like I said, I have a 96 s10 2.2 5spd. That under anything more than 45% throttle under load it sputters like crazy. I put a high flow intake on it when I got it. And all **** broke loose. When I got the truck it didn't have intake piping.. an it ran well. Since I have had this problem I have...
99 s10 noisy rough engine, losing oil pressure, truck dying
I just bought a 99 Chevy s10. We bought it, and it was working great. As soon as we got onto the highway, we noticed the oil pressure drop to 0 and the truck dying. We were able to restart it, and start driving again. A few miles down...

I’ve noticed that the part numbers on some ECMs are the same for V6 and V8. Can you pull out a 4.3 TBI and drop in a 5.0 or 5.7 TBI and everything plug in and work? Assuming small cap distributor to small cap distributor, throttle body to throttle body, etc.
