These new pickup trucks also cost more than a Mack did, too!
You got that right, these engines are more like GM'S toro- Flo v8's in the late 1960's and 1970's. They would run easily with the 250 Cummings grossing 80,000 lbs, for one long summer and it was down hill for them after that, 2 years they were done...these are not a heavy duty diesel, these are a light duty engine, I wonder if they still are using the 2 small pins to hold the timing gear to the crankshaft, instead of a key?.....
