When deciding to do a conversion, the first step is to select the type and size of engine you would require. You should consider things such as dependability, power, economy, speed, price range, adaptability, and availability of equipment and parts.

With reference to engine conversions, the Chevy V8 seems to be the most popular option. These adapter kits will adapt your Land Cruiser's transfer case to a GM automatic transmission that will bolt directly to a Chevy V8. Most of the time, these conversions require driveline and floor pan modification.

- Adapter material is 356 T6 heat treated alloy.

- Kit includes an adapter housing, 10 spline spud shaft, new 700R4 output shaft, transfer case shifter bracket, sealed bearing, gaskets, fastening hardware, and adapter instructions.

Transfer Case: This adapter assembly fits 1963-9/73 10 spline transfer cases (originally mated to a 3 speed transmission). The drive gear has 10 internal splines and a diameter of 1.375”. These cases are equipped with a vacuum style shifter.

Transmission: This kit is designed for exclusive use with the 2wd 700R-4 / 4L60 manufactured through 1996. The overall case length of the transmission is 23.375”, has a non-removable bell housing, and a 4 bolt square rear case. Introduced in 1982, this transmission is offered in two different bellhousing / case designs (60 & 90 degree bolt patterns).

All 4.3 V6 & GM V8 installations will require the 90 degree version. The internal components of these 700Rs can be interchanged if necessary. When this transmission was first introduced, it quickly developed a bad reputation for certain weaknesses. In 1987, GM resolved all of the problems that previously existed. In the 1990s, the name of the 700R transmission changed to 4L60. These transmissions are ideal for many conversions because of the 30% overdrive. It has a 1st gear ratio of 3.06:1; 2nd 1.62:1, and 3rd gear ratio of 1:1.

*Note: It is not practical to adapt an automatic transmission to the Land Cruiser's 6 cylinder engine. The length of the engine, coupled with the length of the automatic transmission causes problems with the fuel tank, transfer case linkage location, and driveshaft angles.

Frequently Asked Questions

When can I expect to receive my order?

We strive to ship orders as quickly as possible but orders can take as long as 4 weeks due to item availability. However, this is an estimated time. Due to a high volume of orders we receive, we cannot expedite the process as this would be unfair to other players and clubs. We process orders in the order as they are placed. Those that place their order early on will most likely receive their order before those that place their order at a later date.
