engine conversions (1941-79)
When using one of our Chevy conversion bellhousings, the stock bracket can be retained. If you are using a GM bellhousing, we
offer P/N 716638 which will provide you with an adjustable pivot location on the Chevy
bellhousing. This bracket kit is furnished with a male ball stud and multiple hole
location that permits the use of all the original Jeep clutch linkage components. This
multiple hole location will provide positioning for various engine locations. The kit also
includes new nylon bushings to replace the original Jeep nylon
bushings. Depending on which bellhousing is being used, the
push rod that extends from the clutch torque tube to the clutch
release lever will need possible modifications.
One of the biggest problems with the
stock Jeep clutch linkage is its reliability
on the trail. Most Jeep owners have
either experienced or seen the stock
linkage fall apart when a vehicle is tweaked or
twisted while 4-wheeling. The linkage has too
many pivoting and non-secured points and, when
put under stress, they tend to come undone.
We offer an upgrade kit for your clutch linkage. This chain-operated clutch linkage
kit, Part No. 716639, connects to the original push rod that extends out of the
firewall and mounts to the stock Jeep driver’s side body mount. This kit also uses
a sprocket & chain that parallels the inside of the frame rail. Unlike the stock linkage
pushing the release lever, this chain controller uses a pulling motion. On serious
offroad use, the chain linkage will allow for twisting of the frame and the torque of
the engine. The chain control linkage is solidly mounted to all components of the
clutch linkage. This kit will not work with inside-the-frame rail exhaust.
ENGINE CONVERSIONS
GENERAL INFORMATION:
Engine conversions for offroad vehicles are popular with both old & new models. We have been involved with engine and
transmission conversions for more than 30 years and are not surprised when we see a new vehicle with less than 10,000 miles
having an engine swapped. Since you are venturing out beyond the boundary of the corner gas station and local repair shop, you
should be aware that offroad driving is quite different than street driving. Once you pull onto a dirt road, your vehicle must be capable
of returning you and your passengers back to civilization. The best, single reason for an offroad 4WD engine conversion is reliability.
If your 4WD cannot deliver this, then you’re in serious trouble. Make sure that when making a change on your offroad vehicle it is
done with the best equipment and design available. Don't short change your conversion for components that will give you less
reliability.
There will always be situations where more power would be nice such as when towing a trailer, turning those big new tires, or falling
short from the top of a hill. A common mistake of many offroad drivers is overpowering the existing drivetrain. If additional power
is required and the stock transmission specifications and rear axle torque rating have been exceeded, then you might be required
to use a stronger substitute. Jeeps have been equipped with several types and sizes of engines. In order to assist you, we have
listed the various stock engines that were used in these years.
