When buying a new truck back then, could you spec what CPL you wanted or just the horsepower and took what they wanted to give you?
You could spec horse power--the CPL was tied to the updated engines as per year. BC-I's ran from
76 up to 79, with many updates. BCII was late 79 to late 82, BCIII 82 to late 85, BCVI late 85 up.
Just as Cat, Cummins was what was available at that time. But Cummins had several engine model
choices. This last Monday I was in Spokane at the machine shop where I have work done. They had
two very expensive dinosaurs in for work- a E9 Mack with very major block work $$$$. The other
a KTA 600, all six heads were junk {major cracking and had already been surfaced too many times.
$3,800 each was the price, cam followers $3,000 each--but the block needed major attention,
so best guesstimate was $67,000.
