I would use the 97 engine
You can move the ac compressor out of the way just unbolt it and the lines and keep removing things around them until there is enough room to move it to the side
You will be using the 97 long block, just the block and heads. All the other parts will come from your 93
You will notice the 97 has EGR and a cam synchro
The 93 does not
You want to use all the parts, sensors, wiring and accessories from your 93 engine on top of the 97 long block
In my opinion if your 93 engine has a lifter tick and you are about to dump head gaskets, lifters, pushrods and more into the 93 engine....forget it. Use the 97 block, you would be far better off putting those same parts into the 97 engine, in 95 the heads were re designed again and got much better then that 93 unit.
93 and 97 are my favorite years of the OHV, the 93 computer with no EGR and no CAM synchro rules, the 97 engine has all the updates and they are tough as nails.
Let us know what you decide!
You could also tinker with the 93 engine, replace all your parts, see how good it comes out and keep that 97 around as a spare for when the 93 engine gives it up.... you have a few choices to make here. I know what I would do!
