Allentown-based Air Products took delivery of a fleet of 350 horsepower 8V92-powered R-626ST tractors from the Allentown factory branch (around 1980 if I recall correctly). I looked them over while they were being prepped for delivery.

The R626's had 6V92 Detroits,a total of 277 were built between 1978 and 1984.

the R770 had the 8V92 Detroit,a total of 136 were built between 1977 and 1985

the R773 had the 8V71 Detroit,a total of 1801 were built between 1967 and 1978

the R769 had the 8V71T Detroit a total of 13 were built in 1975

That's about 2227 too many.
