Installing 86 5ltr in 95 5ltr body

That's a conundrum. There are actually quite a few differences, and you have to choose how you want to set it up. One thing that is for sure is that the driveshaft will be 5/8" too short. You can get a spacer from Steeda to correct that problem.

The 95' engine is 3" shorter than the 86" engine because of the way the accesories are set up. It's quite expensive to get the accessories and brackets for an SN new, unless you find a junkyard with a wrecked SN car with all the brackets. The problem runs all the way back to the timing cover, which is different on the SN cars to accomodate the shorter water pump. In most cases, if you run the fox brackets, you will need to run a taller hood to clear them. You will also have some clearance issues with the electric fan on the SN. If you run an electric fan, you will either way have to run a bigger alternator to supply the power for it. The max amps on a fox alternator is 85, and the SNs came with a 130 amp alternator to run the fan. You can modify the fox alternator bracket with a grinding wheel to fit the bigger alternator. I can tell you how to wire it if that's the way you go.

You can easily use the fox intake and throttle body. You will need a fox throttle cable, which you already have, and do some custom work on the inlet system.
