Well the motor part should be simple. The problem is with the smog controls, are they both fuel injected or carb? Go with whatever is in the 94. Try to change out just the "long block" and keep the 94 intake manifold and all the stuff its connected to. You need to try also to match up the compression ratio or the engine control systems might make it run differently, if you want it to be identical that is. Things like the water pump might have different bolt holes and the alternator/ps pump/ac pump may not bolt right up;
