NV4500 BELLHOUSING ADAPTERS TO FORD ENGINES:
The NV4500 transmission has also become a popular combination when installing a Ford engine into a Jeep. The adapters listed
below are necessary to perform this conversion. Both these adapter plates utilize a stock Ford bellhousing 4.848” index. We do
not offer brackets to install either hydraulic or mechanical clutch linkages for these applications. Some fabrication on your part will
be required.
GM NV4500: P/N 712552 - Chevy NV4500 (1995 only) to Ford 4.848” indexed adapter plate
DODGE NV4500: P/N 712551 - Dodge NV4500 to Ford 4.848” indexed adapter plate

BUICK BELLHOUSING ADAPTERS:
Automatic Transmissions:
The Buick V6 has always been a popular engine to swap into Jeep vehicles. When installing the Buick V6 to an automatic
transmission, we recommend using a Buick automatic. When this option is not available, we offer an adapter plate, Part No.
716134. This plate will couple a Chevy automatic to the Buick engine block. There are some applications where you may have
a Buick transmission and you want to bolt it to a GM block. For this, we offer adapter plate, P/N 716129.
Manual Transmissions:
Due to the limited availability of stock bellhousings, a problem exists when trying to adapt the Buick engine to a manual
transmission. Jeep was the only large volume manufacturer that ever used a manual transmission to a Buick engine. Needless
to say, these bellhousings are extremely hard to locate. So in the early 1990s, we decided to design and manufacture a Buick
V6 bellhousing to fit the 231, 225, and the rear-wheel drive 3.8L V6 engine to a manual transmission. To meet the various
transmission requirements, we manufacture three different styles. (Hydraulic or mechanical clutch linkage brackets will need
to be fabricated).

FORD MANUAL TRANSMISSION TO GM V6/V8 ENGINE:
In some of the short wheel-based vehicles, doing an engine & transmission swap is a game of inches when trying to retain the longest
possible rear driveshaft length. In many cases, it’s easier to accomplish this by coupling a GM engine to a Ford transmission to
a Jeep transfer case. We’ve designed a bellhousing that can retain the stock hydraulic or mechanical clutch linkage on most
applications. The bellhousing requires an 11” Chevy flywheel and pressure plate with a Ford Clutch disc and late model release
bearing. The bellhousing comes complete with a new Chevy release arm, pilot bushings, and necessary hardware.
