However, permit a day or two extra for fulfillment and be aware that we may contact you with questions or options on items where our suppliers may be having difficulties. These swaps are exciting, enjoyable, beneficial and well-documented as with these CJ Jeeps. Individuals are swapping for reasons as varied as the uses of the Jeeps themselves, and the results are invariably among the greatest of improvements owners will make.

The move to a cleaner, stronger, reliable, efficient, serviceable GM engine is one that makes its own good case. The following article is the culmination of the summary of knowledge that Novak and its customers have gained over decades of successful swaps.

Included is the information needed to plan for a great and most affordable process. However, before we talk procedure, let's cover a bit of the history of these Jeeps and their key parts that will play a role in the planning of a successful conversion. AMC's installation of the straight six actually forced a serious design change in the the Jeep CJ5, as AMC designers had to lengthen the CJ's front clip by 3" increasing the wheelbase to 84" to allow for its fitment into the engine bay.

This bodes well for GM V8 installers as the space required for these V8's is quite adequate. Many individuals are prompted to replace these with GM power because of the fuel efficiency, strength, drivability and parts availability offered by the the engines, as listed above. The most successful conversions retain the gear-driven Dana 20 due to its strength, compact design, refined operation and servicability.

It is crucial to discuss transmissions early on. They are sometimes more central to the conversion than the engine. Though some of these following transmissions do not offer overdrive, many CJ Jeeps with larger tire sizes and proper axle ratios will still allow for a respectable freeway cruising RPM.

No adapters are generally needed to marry the following GM automatic transmissions to their usually matching Chevrolet engines. The Turbo is strong, compact, widely available and affordable to buy, service and build.

This is the only auto transmission recommended for a CJ5. TH : In the no-holds-barred strength category, the TH may be the obvious automatic of choice. The Turbo can be a good option, but only for CJ6 Jeeps. The following four and five speed transmissions are recommended for you to consider in your planning. If converting from automatic to manual in conjunction with your engine swap, note that the installation of CJ or YJ master cylinders and related components is not difficult.

Rivoting a layer of stainless steel to stiffen the firewall for a master cylinder is a good idea. T15 : If your Jeep has the T15 three-speed, it is a good, strong option. T14 : If your Jeep has the T14 three-speed, it is an option. Though not suited for wild V8 power or punishing off-roading, mild V6's and all around trail use make the T14 a good match.

It is suited for all engines and all service levels. Many CJ's are destined for more hybrid or even hard trail use and some individuals will be choosing manual shift, heavy-duty truck four speeds to place behind their GM powerplants. SM : For the old-school, ultra low geared crowd, the SM four-speed manual transmission is a great choice.

Surprisingly well behaved on-road and absolutely burley off-road, the SM is a cool box of gears. If you think a transmission designed in the 's is an anachronism, you are right, and a very neat one at that.

They are easy to find and work with. AX15 : This reasonably strong five-speed transmission may be worth installing into your CJ6 the CJ5 is usually too short.Because Novak has always maximized our domestic supply and internal manufacturing paradigm, we are seeing little interruption due to the Co-Vi situation.

However, permit a day or two extra for fulfillment and be aware that we may contact you with questions or options on items where our suppliers may be having difficulties.

There is hardly a powertrain conversion more exciting, enjoyable, beneficial and well-documented as with these, the last era of the CJ Series Jeeps.

Included is the information needed to plan for a great and most affordable process. However, before we talk procedure, let's cover a bit of the history of these Jeeps and their key parts that will play a role in the planning of a successful conversion. A "little" history is a difficult thing when discussing the Jeep CJ, but essentially, the CJ's of the era were nearly identical to the CJ's of the era.

Sales were still strong for AMC's stalwart CJ and they were outfitted with a variety of options for buyers. The rest of the pertinent history is largely mechanical, as discussed below. AMC left behind the thirsty AMC V8s formerly available, as fuel economy standards and increasingly complicated emissions controls took their tolls.

Installing Chevrolet & GM Engines

And, new for was a four-cylinder, not seen in the Jeep CJ since This engine remained available through However, AMC had it in use just as a stop-gap, and in they released an entirely new I4 engine. This was the AMC 2. Both engines were offered with fuel economy in mind, but they both were comparatively meager in their output; a four-cylinder in a quarter-ton truck is just that, and the efficiency and longevity problems with operating their engines past their abilities has been fully experienced by too many for too long.

Little argument need be made about why an individual with one of these smaller engines in their Jeep may feel the impetus to upgrade. It might be said that the 's did not treat Jeep very well in transmissions.

Transmissions for the and later CJs were all new, comprising:. The above transmissions are not appropriate to retain in a V6 or V8 conversion. Novak made a bellhousing adapter for them for a short time, but the futility of adapting an engine to a gearbox that just would not last became self-explanatory. Because of these transmissions' weak service records behind stock Jeep powerplants, we do not offer any conversion to V6 or V8 power. This is essentially a small car transmission in a truck.

The customer's time and efforts are best spent converting to a stronger transmission. The Model was, by a long shot, the strongest link in the Jeep powertrain chain in the through CJ's.

The most successful conversions retain the gear-driven Dana due to its strength, compact design, refined operation and serviceability. More on this later. It is crucial to discuss transmissions early on. They are sometimes more central to the conversion than the engine. In the entire production run of these last CJ Jeeps, all transmissions except one should be ruled out when performing a GM engine swap. GM power can spell their demise within days to months.

Though the automatic available with these Jeeps is a more durable automatic, its strength and features are so far eclipsed by the GM HydraMatic variants discussed belowthat we do not offer an adapter for its retention in a GM engine upgrade. The T manual transmission, however, can be successfully retained in a GM engine conversion. Details, below.

What We Do

One of the most enjoyable Jeeps to work with today is the Jeep YJ Wrangler, as built from to These Jeeps are a most excellent powertrain swap platform, with their inherent durability being greatly upgraded and complemented by versatile GM power.

These conversions take some basic planning and effort in their execution, but the results can be quite fantastic. With improvements in power, fuel economy, reliability and broad range driveability, once one has driven a YJ with a proper GM conversion, it's too hard to look back. Even the Chevy V6 and Buick V6 motors offer great upgrades from even the best tuned and built factory engine options. Before we talk procedure, let's cover a bit of the history of these Jeeps and their key parts that will play a role in the planning of a successful conversion.

The YJ underwent many significant changes from its CJ predecessor. The legally embattled AMC, having been grilled for the hyped rollover risks of the CJ, specified a 6" wider track for this new generation of truck. This entailed a wider frame and a somewhat refined suspension, featuring wider and longer springs and an anti sway bar that together provided a set of road manners not yet seen by its preceding generations.

The YJ did retain the same body width wheelbase length specification as the CJ7, at However, the frame was formed of a heavier gauge steel and stronger throughout its length than all prior CJ Jeeps. This YJ was introduced with a standard, painted steel body, but forChrysler specified and produced the body in galvanized steel, greatly adding to the rust resistance of this new model.

The styling of the front clip was arguably less graceful than the CJ. The headlamps and signal lights were squared as were the fenders and even grille slat openings. The boxier design trends of the mid-eighties had their way with the new Wrangler, and made them the butt of jokes from a generation or two of die-hard CJ buffs. But the jokes began to fade as a classic breed of off-roaders began to turn these YJ's into increasingly commendable trail rigs.

The engine fits great into the bay, and owner S. Lomoriello shows some beautifully clean installation work.A guide to a common engine swap in Jeeps — A ten year old article that keeps giving. This is a common conversion, one we have done several times.

Before we talk procedure, let's cover a bit of the history of these Jeeps and their key parts that will play a role in the planning of a successful conversion. With the spirit of the Jeep Universal Truck still very much intact, the Jeep TJ has done Jeep aficionados generally proud by retaining its off road heritage, and doing so with a touch more panache and refinement than ever before. It is back to round headlights with the TJ, but much more than that. A very major redesign - even more so than from the CJ to the YJ - the TJ got some dramatic changes that include a full coil and track arm suspension system, a low profile hood, and a more refined interior.

However, what changed little was the powertrain. From the axles to the engine, the TJ relied on the same systems as were found in its YJ predecessor, which makes for an easier engine conversion than one might expect. Customer J. Brink shows the beginning stages of positioning the motor. The GM V8 fits like a glove.
