Just bought a 7.8 complete set up cheap and within a few weeks, I'll have it up and going to.my 77 3/4 ton. Got a splicer rear end, converting.to duals and adding a few more leafs and overleaf, already has a 4 inch lift,

It started as a New Holland tractor engine. Ford trucks used them from about 86(or close to it) to 93 when the Cummins B & C series replaced them. The Fords were a 6.6 and 7.8 liter.

Yep, it has the fuel screw adjusted almost all the way out, the governor springs 3 clicks tighter, straight pipe(like in my other vids), and timing advanced a couple degrees from stock(cant remember off hand what it is now). It was 210hp, and now I'd say 250.

@rocintrucker83021227 Funny you mention that, because this engine series(6.6 and 7.8) was designed back in the 60s, right about the same time the 300 came out. Just didnt make it into trucks until the mid 80s.

i work on these engines the are one hell of a torqe monster

I've been around dustcarts with NA 6.6 and 7.8 diesels and they are remarkably quiet on idle...you have to be within a few feet of one to hear it idling.

They actually do pretty well. If it's not intercooled, you should deduct a little from the price. That plays a big role in the power, and being able to use it all. All the regular hard parts are available from a NewHolland tractor dealer. Belts & hoses & filters, you can still get at napa. Performance parts can be found too, mostly used though. These trucks have been super cheap in the last year or so, so watch prices! Carry an extra set of belts, and you'll be fine.

ok that makes more sence now, because a guy on a forum had a 6.6 liter engine that was almost 50 inches long and somone else said it was the 7.8 liter, wich i belive it is.

Yep, the 6.6 is a little smaller. Still bigger than the Cummins 5.9 by just a little. Yep, they do use a Bosch pump. The older ones use either an "A" pump, or an MW pump. Then the 93 got the famous P-pump.

@PINski1015 You know if height's the issue I bet a 3 inch lift or so and some semi tires about 40 inches tall would give you plenty of room to mount the engine lower, and if that didn't work maybe a couple more inches would. And if you were really dead set on a 7.8 F-series and had the tools you could make a sheet metal pan to fit with less height and more width to compensate, and that can add plenty of space. Just some possibilities.

Where's the pix? Need to see some build progress. It will inspire more Ford swaps. Have you seen my 6.6? It's on a couple other vids, I was going to slip it in my 67 F100.

cool, have u upped fuelling at all?

are the 7.8 and 6.6 a different block? and is that a bosch injector pump?

Looks like a giant 300

@PINski1015 The 6.6 would be a better one in a pickup. The 7.8 is just too tall for a pickup. I'm making plans on putting a 6.6 in my 67 F100. All Ford power! It's made by New Holland in Brazil, but says Ford on the valve cover.

I have a link to my home page, called the Low Buck Fuel Rate site. It tells how to do both the fuel and rpm. It literally takes 10 min. to do the fuel screw. The RPM adjustment takes about 45min. I know what you're truck is like, the DT466 in my other videos used to go to 63-65mph max. Now it does about 71-73. My site is at freewebs (decimal point) com slash nevrenufhp It's a good idea to have a pyrometer to make sure you dont burn it up(usually wont get all that hot though).

What is that clutch fan part number?

hello i have a 6.6 how would i turn up the pump and get more speed out of it. its a old ryder truck 55mph is all i can get thanks

i never new ford made an inlin 6 diesel
