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 FJ6# 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 Land Cruiser 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.

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.

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 and 3F 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.

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.

The mount and drives kit have been designed to allow you to reuse the original 2F or 3F Land Cruiser power steering pump, air conditioning compressor, alternator, and viscous coupled fan with the small block Chevy engine. All of these components have been fitted in their original positions; the power steering pump on the right hand side uses its original hoses and pulley.

The air conditioning compressor does not require re-plumbing or de-gassing, simply unbolt it from the old engine, and bolt it back onto the new brackets. Note: The Chevy engine driven fuel pump can not be used as the A/C compressor mounting bracket utilises the fuel pump mounting position on the engine block. The alternator is also removed from the old engine and bolted to the left side of the Chevy engine allowing the wiring to plug in without alteration.

The kit comes complete with a new water pump, gaskets, power steering pump brackets, air conditioner compressor brackets, alternator brackets, aluminium crankshaft pulley, fan pulley adaptor, top and bottom radiator hoses, fan belt, A/C drive belt, power steering drive belt, all bolts, washers, nuts, clamps and instructions.

Marks 4WD Adaptors now manufacture a new interface designed to calibrate your existing Toyota 6-cylinder petrol tachometer so that it can be driven from your V8 Chevy or V8 Holden engine. This eliminates the inconvenience of removing your tachometer from your dashboard to have it re-calibrated. The unit is easy to install and only requires a connection to the ignition coil, tachometer wire, earth B- and ignition B+.
