we were on a LARGE parking lot job in 97 or 98 and everyone centered near my truck at beak time. i was the only one with an "old" truck.
everyone else had mid 90's or newer macks with 400 or 427's, and one 460.
there were also a few kenworts with cummins and cats in the 425 hp range.
well the 237 sounds quite different from the newer engines, one of the youngsters opened the door of my truck to check it out and came around front to ask what engine and trans combo i had as he had never seen twin sticks PLUS a two speed rear switch in a truck before.
the senior "old fart" on the job was a real joker, and was even quicker with a comeback. ...he told the kid that the truck had an old school 325 HP six cylinder mack engine and a quad box with two speed rears.
he also told him that the larger engine and 40 possible gear combinations was why i could keep up with everyone on the road. the kid believed every word as gospel truth, and for weeks after that whenever i was around the big joke was asking me what gear i was in.
mike had the new 460 powered truck with an 18 speed, and on the hood was painted " if ya can't run with the big dogs, stay on the porch" i was one of the very few old trucks allowed to "run with the big dogs"
another one was a 69 Autocar with a cummins and 18 speed. that 30 year old Autocar was washed every night and parked in a garage. it also had a chrome plated engine you could use as a mirror.
