there might be some differences, but the swap should still work. Basically there were 2 different types of blocks up untill 1995. the "W" block, which after 1992 was a L35 balance shaft motor and the "Z" block which was a non-balance shaft motor.

The main difference which might exist is the fuel injection setup and the intake manifold, however swapping them over shouldnt be a problem either since the the real "Vortec" engines didnt come out until 1996, thats the better heads were put into production and the bolt patterns and block castings were all changed.

The only thing that will need to change is if you have a a sidepost mount distributor on the 95, if so you will need to swap distributors and that's it... You will have a crank sensor on the 95 but this can be safely ignored...
