What is the story on the Allis engine in your icon?

AKA-The Purple People Eater. The Big Al as it was called was only on the market for a few years. Allis had trouble with piston issues mainly, The engine needed to be brought up to temp slowly
or it ran the chance of sticking a piston. Plus parts availability was real poor. So the Big Al died a quick death. Although when it ran---it was a runner. I had seen several years ago, mostly you
found them dead on a engine stand with a hole in the side out behind a shop. I knew a guy that had one in a Freightliner C.O.E., the first one didn't last long-the second engine made it 600,000.
It was a engine that didn't like being hurried til full temp. I put it in the avatar because it's different.

Chalmers was into Everything. HE, farm equipment, industrial equipment, multi use engines, Electricity generation generators and the systems that ran them, electric motors, huge pumps even built Nuclear Reactors. Is pretty well what did them in being too many irons in too many fires.

And if I am remembering correctly they also made stone crushers! I believe there was one I spent a good amount of time shoveling the spillage underneath one summer in 1969! Did some digging and found a list of some of the stuff they were into back in 1932 in a Pit&Quarry Handbook from that year. The one I shoveled und looked like the top picture on the left side of the page:

Just caught this thread, nice work.

Coming from major Bulldog teritory, a cummins and an eaton fuller is a rat rod. Should be a 711 and a 12 speed, and green interior of course, and spoke wheels. Something funny happened when Macks went to the west coast.:)

It's no more a rat rod than a B73 with a 335 and Spicer boxes. Which I have seen, factory built. And rat rods don't look like this B75. It's not the first time I've gotten flack for this conversion.
You do something different and people think you cursed the bible. Actually after working on the cab and building a frame for it, It's become a better truck than it ever was.

I am not giving you a hard time, your work is fantastic, and your work ethic, and fabrication skills are second to none. I was going for being witty. For some reason West Coast Macks are built differently than east coast macks. Just visited a guy who has i would guess 30 b model macks, and of the 30 he pointed out the B75 or 73 that came factory with a cummins, as being a rare beast.

Mack is the only Manufacturer that made there own engines, transmissions, and drive trains and manufactured items down to there own spokes and axles. Mack is the major manufacturer of trucks in New England, and a Mack without Dayton wheels until recent is rare. Guys around here think the Mack 12 speed is the best transmission ever made and why anyone would use any other is crazy, had one customer talk about removing his 18 speed to install a 12 speed.

Carry on with the fantastic work, you are obviously at the top of your craft.
