The dampner will have to be changed as well as the crank sensor, other than that I don't remember anything else that is that big of a deal besides the low oil sensor that is not on the late model engine.

Willy said:You will need to swap timing covers, crank sensor mounting location is different. 89-93 uses bracket that bolts to block and hangs over front of cover. 94-95 bolts directly to timing cover and mounts higher on cover. Ask me how I know, just put 93 engine block and heads into a 94 5spd. Need a scanner I took many comparison pictures of both covers side by side. Not to bad to do fairly easy swap. Just gather all needed gaskets.

Sorry about the above post 94 block in a 90 will work, the three bolts holes are there to bolt sensor bracket to. If you were putting 90 engine into 94 similar to what I did then you would need to swap covers. Sorry about the above post do not mean to cause any confusion.doug93sc said:I put a entire 94 longblock in my 93SC and the timing covers do have the mounting holes for the crank sensor (on mine they were full off dirt and hard to see) but you will need the crank sensor bracket, HB and wire harness from the early model engine. Otherwise it is a very easy swap.
