JerseyBoy77 Posted November 25, 2009 Share Posted November 25, 2009 Hi, excuse the question if it seems a little silly, I'm new here.What is the largest engine used in R Models? Throught the 1970's to be exact.Also on a side note, what is the best aftermarket exhaust, performance wise, that would go with such an engine.Thanks in advance!!Jess Quote "You som'bitches could'nt close an umbrella!"

Performance exhaust is up to your imagination. There is the option of no mufflers, Riker, Donaldson, and a few others but I'm not akin to aftermarket performance mufflers for heavy truck usage. Most diesel mufflers are very free flowing and are "tuned" for different exhaust note/noise.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

BAD DOG Posted November 25, 2009 Share Posted November 25, 2009 The largest engine in an R model would probably have been the ENDT866 Cubic Inch V8 at 375 HP. I'm not sure but I'm going to say it was produced between 1974 and 1978 or 79 time period.

Kav Posted November 26, 2009 Share Posted November 26, 2009 Hi all - The first Superliners in Australia had the 3408 Cat. They were a bit heavier on fuel but they were great pullers on road train and heavy float work. Best regards - Michael.

Joe Ditchkus Posted November 27, 2009 Share Posted November 27, 2009 R=Models were offered from factory with the Detroit Diesel 12V-71 with 852 cubic inches, not the biggest in cubic inches but close. They were pretty impressive in their day.Nice to see that 12 banger when hood opened. Joe D.

b61fred Posted November 27, 2009 Share Posted November 27, 2009 hi, Was the KT or KTTA Cummins engine offered in Mack trucks in that time frame. I am going to say that you are limiting this to on road tractors or straight trucks. Mack offered some very large trucks for off road and quarry work. There is a quarry in Bedford Indiana that has what they called Mountain Macks. About the only item that looks like a r model is the cab. I think they have some sort of wakashaw engine, HUGE!!!!
