If you are thinking of swapping a fuel-injected engine into your previously carberated Jeep keep this in mind: You are essentially on your own when it comes to engine swapping. There is no step-by-step set of instructions and don't expect to find an engine swapping kit with everything needed.... neither exist.  The one thing you do have going for you is the tremendous support from fellow Jeep owners. There are some great newsgroups and forums full of knowledgeable folks that have seen it all. The short block Chevy swap is very common and most every kink has been worked out long ago.

I bought my engine from a local salvage yard after searching for 6 months. I paid good money and I expected a good product. I told the counter guy I wanted a very clean pull of the engine, this meant no cutting wires. All electrical connections were unplugged and labeled.

I could've reused the factory wiring harness but there were some problems related to my application. I decided to look to the aftermarket for a wiring harness. I believe in 1993, GM changed computers on their TBI motors from the venerable GM ECM #1227747 to something that is not as readily available or as easily programmed. My 1995 350 now uses a computer, Eprom and wiring harness that you would find in a 1992 Chevy 350.


Check out the 350 I picked up.
 

When swapping any small-block Chevy V8 into a short-wheelbased Jeep engine placement must dictate the positioning of the rest of the driveline.  9 out of 10 times, when someone ends up with clearance issues the reason is because they used "universal" style or adjustable motor mounts such as the ones from Advance Adapters.  AA makes great products and most engine swaps will utilize many of their parts. The problem with their motor mounts is they allow too much variation in the engine placement. There is only one perfect position for the V8 engine and if this position isn't used then clearance issues are likely to pop up after everything is installed making a fix extremely difficult and expensive.

A good number of people who use AA or home-made engine mounts have front driveshafts hitting the oil pan or bellhousing, exhaust manifolds interfering with the steering shaft or headers dumping right onto the front driveline. They can also have problems with the engine sitting too close to the radiator and now cant find the right fan to use or just the opposite...their HEI distributor is hitting the firewall when the Jeep is used off-road.  Mountain Off-road Enterprises makes very impressive engine mounts that place the Chevy V8 engine in the perfect position, thus taking all the guesswork out of the equation. They are pricey but worth every penny. I cannot emphasize enough how important this is. Now that I have the new engine installed in my Jeep, it is obvious that there is very little margin for error....MORE has a winner in these mounts. * These mounts are recommended for V8's only. With smaller V6's there is much more room to play with in the engine compartment. Just be aware that most Jeeps came from the factory with engines offset to the left or right depending on where the front driveline is.
