Gary Lewis Posted March 23, 2021 Share Posted March 23, 2021 Welcome John! I believe Gary is thinking of the 250's that Ford sold in the Bullnose era. They were just big enough that they didn't fit with the 1/2 ton 150, though they could be had with a 302. My M5OD-R2 trans came out of what I considered to be light duty F250. It was a 1991 F250 2wd with 302, 5spd, and 3.08 diff. I've told the story before, but the guy was doing a Cummins swap in the truck, so he had the engine and trans for sale...but since the truck was an F250, he had the trans listed for sale as a ZF5. He said people kept messaging him to tell him the trans he had was not a ZF5, so he relisted it as the M5OD, and that is when I found it...only a half a mile away from my office, right here in the industrial park. Yep, the non-HD F250's had a lighter duty driveline. I was not aware of that until I got Big Blue and noted the HD designation. Then I started looking for the LD's.

Then I started looking for the LD's. Note that Ford made the break at the 8,500 gvw emissions limit. This way they could use the 351 HO (as well as the 460) without a cat or fuel injection. The IDI slid by too. There were carbureted 460's in F53 chassis right up into the 90's. Link to comment Share on other sites More sharing options...
