Ford V-8???

I am a huge Ford fan and have followed the SD's from the get go, but why did Ford go with the V-8 versus the I-6? Is the powerstroke a former gas engine as a friend insists? I really don't believe that but he keeps up with his ideas. Thanks. DaveVB

The 7.3 Powerstroke had its origins as a gasoline engine but the 6.0, 6.4 Powerstrokes were designed from the ground up as diesels.
Ford goes with the V8 becuase it fits in their trucks, did you ever see a Dodge B-series van with a Cummins diesel?

The ford p.s.d. is a real, I.H. diesel! not as your buddy states. the gas convertion engine was in chevies and gmc's. based off the big block if i remember correctly.


As to inline .diesel guys correct me if needed. dodge already had the i6 cummins and ford needed a good solid engine to compete. cat was to costly. so we got the v8 school bus motor from I.H. the rest is history that others will filll you in on.

Ford was using V8 International diesels before Dodge started using Cummins.

If you don't want to believe that the 6.9 and 7.3s were converted gas engines then don't look too close at the International MV404 and MV446 gasoline engines from the late 70s and early eighties.

Ironically Dodge used the International MV446 gas engine in Motor home chassis after they discontinued their 440 engine.

actually, dodge put a cummins inline 6 diesel in their pickup line back in the mid 70's, but they did not sell very well, so they dropped the diesel for about 15 years.

and international used the inline 4 cylinder cummins diesel in the scout in the mid 70's also.

The inline six cylinder diesel engine Dodge used in pickups in the late seventies was not a Cummins, it was a 243 cubic inch Mitsubishi diesel.

check the history on the cummins contract with DC. ford had it first but they had ties with navistar so they sold the contract to DC and for several years ford made money off every dodge sold with a cummins engine in it. give it ten years and someone else will be offering cummins engines in their vehicles cause dodge will be offering a small detroit or a benz diesel. the reason cats' not in the race is because the smallest engine actually made by cat is the 3116 or the new c-7.the small cats in little doziers,skidsteers, and other small equipment is made in asia. my skidsteer is powered by misubishi, still a good engine and does what i need it to do. ya'll quit knockin on those gm gas to diesel converts they keep our military movin unfortunately!!

Oh boy, lots of questionable info. here! First off, the International Scouts of '78-'80 used a Nissan 6 cylinder diesel. The '78-'79 Dodge pickups used a Mitsubishi 6 cylinder diesel. The '78-'81 Chevy and GMC pickups used the Oldsmobile converted gas engine diesel, but the '82-up 6.2L diesel was designed from the ground up by Detroit Diesel, and not a converted big block Chevy. The International 6.9L was based on the basic MV 404 and 446 gas V-8 design, but didn't share any major parts. The B series 5.9L Cummins was actually designed by a company called Consolidated Diesel, which was a joint venture between Cummins and Case. The 'B' was to replace many Case diesels and Cummins was going to (and did) sell the engine to other manufacturers of construction equipment. You have to give Dodge credit for seeing the 5.9L's potential as a truck engine, the Dodge Ram was the first highway vehicle to use it. Freightliner was the first to use the 5.9L in a medium duty truck a year or so later in the FL 60.

Thank GOD!!!!..............good info.

One minor detail; the 7.3 and 6.9 were based on the gasser but the 7.3 PSD IS NOT.

So to the original poster; the original 6.9/7.3 were converts but NONE of the PSD's are.

Joe, set the guy straight on the Ford/Cummins BS.............unbelievable the urban legends that get started.

No joke, that's the rumor that just won't die! There was something to it, though. Going back to 1991, there was a rumor that the F series was getting the Cummins 'B' series by 1993. Even the dealers were saying this. And, it was true to a point. The Ford-New Holland diesel that Ford had been using in the F-700 could no long pass the emission standards. So, in 1993, the 'B' series went into the F series, but it was the F-700, not the pickups. Ford painted the engines gray and stuck a Ford emblem on the one of the valve covers, and called it the 'Ford 1060'. Around that time, Ford did by some Cummins stock, and the rumor was that Ford was seeking ownership of Cummins. The story was that if Ford could get control of Cummins, they would not renew Dodge's contract for the 'B' series. Ford sold all their Cummins shares a short time later. So, it really isn't a surprise how the rumor got started, but it is amazing how many still believe it is true today.

From my information. . . the 7.3 PSD is not a variation of some gas motor. But even if it were. . . who cares? It must have been a damn good gasser!
