In Australia an engineer's report is required after the conversion has been completed. Contact your local RTA office for a list of engineers.

The GM V8 to HJ kit part no. (MFK371#####) utilises the Land Cruiser 11" clutch set up on a new flywheel along with a new bellhousing that measures 240mm/9.45" in length. This new bellhousing and flywheel has been designed to move the engine forward giving adequate clearance between the cylinder heads and firewall. Re positioning of the transmission or firewall modifications are not required with this kit.

Internally balanced GM engines used with the following kits: MFK371C, and MFK371C/5

The new flywheel supplied in the kit is fully balanced and fitted with a new GM 153-tooth ring gear, it is drilled and doweled to accept the standard Landcruiser 11" clutch as fitted to the 2F, 3F, and 2H engines. The flywheel is heavier, giving greater inertia allowing the engine to idle smoother. The extra weight also helps to give less chance of stalling the engine when off road climbing over rocks, and taking off on steep inclines. The extra weight of the flywheel has no adverse effect on the engine.

As the flywheel supplied with the kit has a 153-tooth ring gear you must use the correct Chevy starter motor to suit. This starter motor can be identified as having an alloy nose cone and uses a short and long bolt to attach the starter to the engine block.

Externally balanced GM engines used with the following kits: MFK371CE, MFK371CE5 and MFK371C/L4.

This new flywheel does not have a ring gear fitted, it bolts to the crankshaft behind the GM flex plate. The flex plate carries the ring gear and the balance weight for the engine. The flex plate ring gear must have 168 teeth. The flex plate is secured to the back of the flywheel with 6 bolts and spacers.

The bellhousing accepts all the Land Cruiser 2F 6-cylinder petrol components such as the bellhousing mounts, slave cylinder, clutch fork etc.

It will also be necessary to identify the year of your Chevy engine, particularly the late model engines as the crankshaft bolt pattern changed in 1986. The post 1986 Chevy small block engines were also externally balanced. One way to identify a late model Chevy engine is by the one piece, external rear main oil seal.

The kit has been designed to allow for firewall clearance without shifting the transmission or altering the drive shaft lengths.

The gear box input shaft is coupled to the clutch via an input extension shaft. The shaft has the Toyota internal spline and spigot diameter on the gearbox end with the GM external spline and spigot diameter on the engine end. The front of the shaft is supported in the crankshaft by a sealed ball bearing inside an adaptor ring.

The clutch is operated through a thrust bearing extension sleeve, which is supported in a machined boss located in the centre of the housing. On the front of the sleeve is a bearing to suit the GM clutch pressure plate.

NOTE: As this kit was originally designed to replace the F series petrol engine some second hand parts will need to be purchased for the installation. A bellhousing from a 2F or 3F 6-cylinder petrol with all of the clutch components such as the slave cylinder, clutch fork etc.

NOTE: You will need to purchase a bellhousing to match the year of your vehicle as pre 10/84 vehicles have straight transmissions and post 10/84 vehicles have twisted transmissions. The post 10/84 gearbox bellhousing bolt pattern is rotated down 7 degrees on the right hand side.

The engine mounting kits have been designed to give you sufficient legal engine sump to differential clearance when used with a standard rear bowel GM sump.
