B Model with a Cummins

[need4steam 1]

I saw a B-87 the other day with a Supercharged Cummins. At first, I didn't believe what I was seeing but sure enough there it was. So I did a little internet searching and found that they did make such an engine. One article refered to this as an "Iron Lung Cummins". What is the opinion of this motor? Good runner, bad runner, or run like H*** away from this one.

Thanks,

Doug

Dave Strickland of Cana VA has at least one B model with the "Iron Lung" Cummins in it.. Thinking it has an L cab???  He has had it to many Shows in the area possibly even ATHS York PA in 2015...

D.A. Strickland and Jim Dixon both have B-77's with Supercharged Cummins.  Daryl Emery has an LT with one in as well.

There was a b71 advertised on this web site recently. It had a noticeable longer hood and a 220 Cummins diesel which was the natural aspirated version of the supercharged engine. These engines were popular here in the west. It made a huge difference on grades like E. bound Donner summit with 7000 feet of adverse grade with 275 hp. and 300 hp. vs. 170 + for a Mack in the late 40's and early 50's. Cummins engine were spec.  in B models mostly with the L cabs and were used almost exclusive by the LT models with a few using a Hall Scott in the early years.

Wasn't the B model with the extended hood that was for sale at Macungie equipped with a factory Cummins?
