12.7L Detroit vs 14.0L Cummins (opinion)

I occasionally drove an 80 something Brigadier General in the city peddling freight for CF. They rented 2 of them at the terminal I worked at. It was straight pipes and one of the loudest trucks I have driven. It was a workhorse!

 

what is the advantage of having FASS system?!

 

I read a Cummins service bulletin that said that FASS or equivalent was the fix for the 903. My dad drove one. One day they'd dyno it and it would put 400 to the ground. The next they'd be lucky to get 150. Cummins said that was the fix.

 

Up until '65, the 7000 was available with the V12 gas job, 2-351 V6s with a common block, allegedly good for about 275 HP. Diesels were still in their infancy, and some still wanted gas jobs. Some unusual creations to get them "over the hill", like this guy was from Janesville, Wis. and adapted a Buick V8 on the front of an IH in line 6. It supposedly worked well.

Mine really didn’t change much in sound or smoke when starting until it was below freezing. When it was single digits or below and had set overnight it sounded like it was coming apart for 30 seconds or so and looked like it was on fire. If it sounds like a sewing machine all the time you probably need to have it checked and may just need the overhead run.
Picture was a cold start in single digits, smoke cleared up in 30 seconds or so and it had just been inframed.
