I was told the only difference between the 504 and 555 was the 1/2 inch stroke and that most parts were interchangeable.. My 71 Brockway had the 504 and I had bought 2 555's from a man up in NY state.. Was going to build one engine from the 3, but I sold the whole truck and all the parts i had accumulated to a  Brockway man up in NC.. Have not heard what he has done with them..

Were the two engines a similar design but just different strokes?

What was the specs on the V6 from the early 1960s?  The Ford 950 had it rated at 160 net HP.

Bruce

Bruce, the small Cummins V6 and V8 engines were built from the mid-60s at a Cummins plant in Darlington, England. There were V6130/V6140 and V8170/V8185 with 4 5/8" bore x 3 1/2" stroke-the V6 was 352 c.i.d. and the V8 was 470 c.i.d. There was a V6 version of the V504 V8 too-V378, I think.
The Cummins V6 in the Ford N950 would have been a V6200, I guess which was a totally different engine to the small V6s, I think. The V6200 was 588 c.i.d.-5 1/2" bore x 4 1/8" stroke-V8 version was 785 c.i.d.-V8265. I think Jeff has a military version of the V8 rated at around 300 h.p. in his military Mack.


You are right Hamish, my Mack M123A1C has a 785 ci Cummins V8-300 with 300 hp.

I can confirm that once again, Hamish is 100% correct

Hamish (11/23/2020)
V8210 was 504 cubic inches, I think Jeff W. V504 4 5/8" bore, 3 3/4" stroke, V555 4 5/8" bore, 4 1/8" stroke.

Hello folks, 

                 I was wondering if anyone could tell me if the Cummins 555 aka triple nickel was the same engine as the v210? 

Thanks, Jeff
