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 availibility 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 aluminum alloy.

- Kit includes an adapter housing, 19spline spud shaft, new TH350 output shaft, transfer case shifter bracket, transfer case input seal, sealed bearing, gaskets, fastening hardware, and adapter instructions.

Transfer Case: This adapter assembly fits 8/1980-1/1990 transfer cases. The transfer case design was changed to a split-case design configuration with a 19 tooth internal spline on the input gear.

Transmission: This adapter kit is designed for exclusive use with the GM TH350 automatic transmission. This GM automatic was commonly found stock in vehicles from 1969-81. It was used in both pickups and car applications. The TH350 has aluminum, 1 piece case. This transmission is one of the most popular choices for engine and transmission conversions due to the overall length of 21-1/2”. The 1st gear ratio is 2.52:1; 2nd 1.52:1, and a 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.
