BELLHOUSING ADAPTERS
(Retaining your Stock Transmission)
Land Cruiser V8 engine conversions are extremely popular due to the cost and availability of stock GM & Ford engine parts. The
components covered in this section are for retaining the stock transmission. These components are offered individually or as a
conversion kit. To properly select the adapters for your conversion, make sure you have identified the stock transmission in your
vehicle.
RETAINING THE STOCK 3 SPEED TRANSMISSION:
The original 3 speed transmission is 8-1/2” in length. With very little difficulty, this transmission can be adapted. The kits work in
conjunction with a stock GM or Ford bellhousing. The Chevy bellhousing should have a small index diameter of 4.686” in the back
of the bellhousing to achieve proper alignment to the Toyota 3 speed. For a Ford engine swap, the bellhousing should have a
4.848" index diameter. The adapter plates for this 3 speed should not be used with the larger 5-1/8” index diameter bore
bellhousing. If the smaller bellhousing indexes are not available, you can purchase a reducer ring (P/N 716041) that will reduce
a Chevy or Ford large indexed bellhousing to the proper index diameter.
These transmissions were offered in both column and floor shifted models.
In order to use the original 3 speed transmission, you must have a floor
shifter because the column shift mechanism will not have sufficient clearance
between the new engine and firewall. The floor shifter stick will need to
be slightly modified for clearance beneath the heater. If your transmission is
column shifted, you will need to change the transmission top cover over to a
floor shifter style. Conversions using the GM 292 in-line 6 cylinder engine will
not require a new floor shifter.
To obtain the proper firewall clearance, the transmission and transfer case
assembly will need to be relocated a minimum of 3-1/2” forward. On many of
these applications, you have the option of reversing the driveshafts (front to
rear, rear to front); however, the Chevy V8 distributor will be forced into the The floor shifter modified to provide heater clearance
firewall and modifications will be required. On Ford V8 conversions, this can
be accomplished with very little difficulty because the distributor is on the front of the engine.
The adapter kits for both the Chevy & Ford conversions come complete with an adapter spacer plate, custom retainer, pilot
bushing, oil seal, and necessary hardware.

We also carry the Mark’s 4WD bellhousing adapter that can be used against the original Land Cruiser 3 speed bellhousing. Their
bellhousing adapter will permit the original 3 speed and transfer case to remain in their original location, eliminating the need for
the 3 speed floor shifter conversion. The Mark’s bellhousing adapters for both the Ford and Chevy applications consist of a new
adapter housing that is approximately 4-7/8” thick, and bolts directly to the front side of the original Land Cruiser bellhousing. This
added length provides an ideal engine location and only requires engine mounts for the side of the new V8 engine. The rear
crossmember support is eliminated, since the original Land Cruiser bellhousing supports are maintained.
NOTE: Due to the short length of the 3 speed transmission along with the new bellhousing mount supplied in the kit, we have had
a couple of instances where interference occurred between the front driveshaft and bellhousing mount. A modification to the
bellhousing mount was required to achieve proper clearance. Other considerations included, a longer slave cylinder hose to
mount the slave cylinder to the passengers side of the bellhousing, removal or modifications to the transfer case linkage gating,
and slight floorboard modifications.
