Is it true that the Cummins V6-200 and the economy V6E-195 version were the only two diesels ever offered for the extra-heavy-duty F- and T-series diesels throughout the 1963-69 period?

Because, when they were superseded by the Louisville L-9000 and LT-9000 in 1970, the diesel selection was expanded a great deal. In contrast to the former F-850-D, F-950-D, F-1000-D, T-850-D and T-950-D, the L-9000 and LT-9000 could be had with these diesel engines:
*Cummins NH-230 (standard)
*Cummins NHC-250 Custom Torque series (225/250 hp)
*Cummins NHCT-CT Custom Torque series (248/270 hp)
*Cummins NTC-335 Custom Torque series (260 to 335 hp)
*Detroit Diesel 6-71N (218 or 238 hp @ 2100 rpm)
*Detroit Diesel 8V-71NE (260 hp @ 1950 rpm)
*Detroit Diesel 8V-71N (290 or 318 hp @ 2100 rpm)

Has anyone with a '63-'69 F-850-1000-D or T-850-950-D ever attempted to change out the V6-200 to something more powerful such as the 6-71 or the 6V-92TA?

All I can say, I worked for a gent who bought two T950D and one T950 dump trucks
that he picked up in person in Dearborn in 1964. As they have a 5 & 4 those Cummins
were impossible to shift, rpms just hang there, by the time it came down to shift you
were just about stopped, then when you shut it down they would rattle the cab to
death. Now the owner could not shift the aux on his truck and left the aux in direct
since day one, just using the main. It would blow the doors off the other two and any
other truck loaded of course it was a 534. who cares gas was 29ct a gal. My opinion
they should have used those bone shakin Cummings for a gernerator or water pump.

 

I have seen an old state truck with a 671detroit and an allison sitting in a junk yard i think they also had the 1150cat the 743cummins and the triple nickel also in the smaller ones they had the 363cid delgaham(i aint got good spelling fur that) diesel. I'm pretty sure I'm right but feel free to prove me wrong( I'm married it happens a lot)

 

The Dagenham 330-cid six-banger was used from 1963-1966 in the lighter 6000 and 7000 series (C and N lines), and succeeded by the Dorset 363-cid six-bangers from 1967-1970. None of the Louisville 6000-8000 series used the Dorset.

The 6-71 series was cataloged for the 850 series and up F/T's, I think, starting in 1967, and of course it was also cataloged for the Louisville 9000 series that replaced the 850D-up F/T series in 1970. Until we have the actual brochures of the 850-up F/T series, this is as best as I can put it.

The 8000 group F/T series, which debuted in 1965-66, were at first powered exclusively by the Cummins CF160, C160 or C180 (all 464-cid six-bangers), but in 1967 the Detroit Diesel 6V53 was also available, and in mid-1968, so were the Cat 1145 (V175), 1150 (V200) and 1160 (V225).

Are you saying the 534 had more power than the Cummins?

 

In a sense, yes. But which Cummins engine are you referring to?

The 534 Super Duty (F/T-800/850/950/1000) was rated at 277 hp @ 3400 rpm and 481 lb/ft tq. @ 18/2300 rpm.

The Cummins V6-200 was rated at 200 hp @ 2600 rpm and 452 lb/ft tq. @ 1800 rpm.

The Cummins C-180 was rated at 180 hp @ 2500 rpm and 425 lb/ft tq. @ 1700 rpm.

I reffered to It was a V6 195 Cummings v/s the 534. would have been
way better if it was a V6 screamin jimmy. Then in this century its been
a L9000 with a 3406 Cat with a 7 sp spicer. that defies gravity. The
other L9000 with a 6-71 "I think I can" I pass him like a car, just so
following him I dont get oil all over my windshield.

 

The V6E-195! This was the low-speed economy version of the V6-200, producing 195 hp @ 2400 rpm, just as the NHE-180 was the low-speed economy version of the NH220 (743 cid) engine.

The Detroit Diesel 6-71NE, another 195 hp oil-burner from the mid/late '60s, made 570 lb-ft of tq. @ 1200 rpm (N55 injectors).
