Mack introduced the 237 in 1966 or ‘68 and it had around 850 ft lbs of torque, compared to the 6-71 Detroit with 611 ft lbs that lost most of its power going uphill. The 237 Mack had the highest torque in a small block until Cummins introduced the L10 in the early ‘80s.

No one does it better or with more oomph than a mighty Mack with a 🐶 350, a 🐶 400, a 🐶 427, or even the mighty 🐶 dog v8 500 hp When you see a Mack attack with a bronze bulldog perched to leap on the hood ( actually was made from an original wood carving done by MACK chief designer ALFRED MASURY, while he was bedridden in hospital for a severe Appendicitis attack in the early ‘30’s ) Before the bronze leaping bulldog as Good ornament where Motometer used to be, there used to be a tin plate not Far from the chain drive sprocket on the old A C and A K ‘s, which had a BULLDOG TEARING UP A WAD OF BILLS SAYING - CUT YOUR OPERATING COSTS with a M A C K!

66 was pre-Maxidyne, late 67-68 was first Maxidyne 237. We had a couple of them. The first ones used studs and nuts to hold the flywheels on, had an American Bosch pump #APE-6BB110T-5757-M1 and the owners manual had a separately bound "Maxidyne Supplement" included in the package. Engine would have been stamped ENDT-675 up by the timing gear case. They also used a big full flow Lubrifiner oil filter on a bracket bolted to the driver's side of the engine
