I would imagine some people here have done this swap. Can you give me some info on things that'll need attention. I'm looking for any good short cuts/information you can provide.

Thanks,
Todd
 
The easiest way is to keep the 91 EEC and wiring harness. Use 91 maf sensor and the 91 30# injectors. If you want to use the 91 exhaust, use the 91 exhaust manifolds. You will have to use the 91 harmonic balancer and crank sensor. You can keep the 94 timing cover, it will work. If you have maintenance monitor and want to keep the oil level sensor you will need to use your 91 oil pan which has the sensor in the pan. May be some other minor details but this is the main stuff I can think of. Good luck, John
