92 5sfe and 94 5sfe differences Options

[Decalsondemand]

ok i went to car-parts.com looking for an engine and it is showing a 92 5sfe with the 4th letter s in the vin as an option so i got out the title to both my 94 gt and my 92 gt both had the 4th letter s in the vinwhat would the differences be besides the harness and some of the sensors? can i make this work? my 92 has alot of problems as far as suspension and so forth but the motor is strong if i can use this in my 94 that would save me alot of money for the time being the thought of pulling 2 motors is the only thing that has slowed me down thus far.....would it be easier to drop the undercariage on my 92 if i go this route? any advice would be great thanks
