Grey To Red Motor Conversion:
Holden Cars had Grey Motors from FX - EJ. Replacing a Grey Motor with a later Red Engine involves welding 2 Engine Mounts onto the Cross Member. The original 3 Speed Crash Gearbox and its Bellhousing will bolt up directly to any of the Red Engines.
Grey To Blue or Black Motor Conversion:
The same procedure as Grey to Red Motor is used, but some provision must be made for the larger Diameter Blue/Black Clutch Cover Plate.
Grey Motor Bellhousings FX - EK:
FX - EK used a Bellhousing that was integrated with the Gearbox and was fully enclosed (no Tinware Lower Cover Plate).
Grey Motor Bellhousings EJ:
EJ was unique in having a Bellhousing separate from the Gearbox and with a Tinware Lower Cover Plate.
Block Bolt Pattern:
The Block Bolt Pattern is the same on all Holden Six Cylinder Engines from FX to VK.
FX - EJ (Grey Motors). EH - VB (Red Motors). WB, VC, VH (Blue Motors). VK (Black Motors).
Grey Motor Engine Mount:
Grey Motor Holdens had a single Engine Mount at the very Front of the Engine.
Red Motor Engine Mounts:
Red Motor Holdens have two Engine Mounts. One on each side of the Centre of the Engine.
Grey Motor Rear Gearbox Mount:
Grey Motor Holdens had no Rear Gearbox Mount. The Gearbox had Mounts at the Front of the Bellhousing for support.
Red Motor Rear Gearbox Mount:
Red Motor Holdens had a single Rear Gearbox Mount.
Note that GMH produced a revised 3 Speed Crash Box when the 179 was released so increasing the Engine size above 149 cu. in. may put excessive strain on the original 4 Bolt 3 Speed crash Box. Early 179's were released with Hydramatics only since the Hydramatic could handle the increase in Power.
