He has a '94 PCM....which is identical to a 1995 PCM....which came with L36 chips. So THAT issue can be dealt with.
BUT....and this a a BIG but....not as big my ex-wifes, but it'* still big.....
The big issue on doing a swap like this will be the wiring. They are quite different between the two engine models, at least fromthe firewall to the engine. Since your 94 uses the same PCM has our 95 Bonnevilles, you may be able to get away with just finding a 1995 engine harness. But to be certain, we will need to verify the pinouts at the firewall connection between your 1994 and the 1995 L36 harness.
