138 Red Motor:
138 Cubic Inches Displacement
These engines were fitted to LC & LJ Toranas. The car carried a 2250 badge, referring to the 2262cc capacity. Early LC ones used adjustable rocker gear the same as 161 engines optionally fitted.
LJ examples used the non-adjustable hydraulic lifter valve gear that was used in 202 engines and had tapered Seat Spark Plugs.
Bore And Stroke:
Russell Payne's Shed
All the red sixes have the same 3.00" stroke except the 201, 202 and 3.3 which have a 3.25" stroke. Blue and black 3.3's also have a 3.25" stroke.
The Red 138 was standard equipment for LC & LJ Torana 6-cyl models. It was badged 2250. Same capacity as FB, EK & EJ Grey Motor, but nothing in common. Dr Terry
