I have found one of these in an international. What model trucks does this engine belong to. And are they any good.

 

Are you sure it is a Ford engine? International had there own version of of big gas engines, all the way up to there 549

?

If it is a Ford that someone swaped in, there is a SD forum in the engine section that caters to the 401 - 477 - 534's FYI.

Other than that, the SD engines were available in a variety of Ford trucks, F series, L Series and the C series (my favorites) such as the C800 - C900 and CT800 - CT900 models as well as few other C series.

Good durable engines, able to slog along all day with the hammer down. BUT - parts are getting hard to find AND they suck fuel down like it is still 30 cents a gallon.

Yer it's a Ford it still has the sticker on the rocker cover looks in good nick

 

Then as long as ou are willing to feed the beast and take the extra effort to find any parts that might need replacement as you use it, and realize a fairly low rpm gas engines limitations, you will be fine.

Most of these went away as they aged and as the fuel prices went up and diesel took over the market. I wonder now if the projected stateside $5 a gallon gas prices will be the finaly death call for the remaining runners.

I personally care more for Ford SD gas engnes better than the International large gas enigne family - 549/478 /461 etc as the Fords seemed to hold up a bit longer. Although I am sure like most things, how they were maintained and the paticular useage pattern had somethingt do with it as well.

Wow, that's an odd ball. International had their own big gas V-8's, as I remember they had a 478 and a 549, as someone said in an earlier post. So, if it is a Ford 477 in there, what you have is a Super Duty V-8. These large truck engines were not based on any other Ford V-8, and nothing interchanges. They are a bit similar to the MEL's, but still much larger. NAPA used to carry about all the parts you would ever need for a Super Duty, but I don't know what they have for them these days. They weigh about 1,200 lbs., and are slow revving, about 3,400 r.p.m. max.. A lot of torque, but not much horsepowerfor their size.

 

+1

Only thing I will add is that the smaller engines had higher governed RPM settings, the 3400 rpm was for the 534, while the 401 & 477 were normally set at 3600 rpm, at least per the manaul. I have also noted some information that lists a 3800 rpm setting fr the 401?!?

Wow thanks guys for the info the motor is a drop in and not origanal for the inter I have zero history but its last life in the inter is a fertilizer spreader so low revs and hard going in soft sandy soils. It still has all the gear on it including sticker on rocker cover with all the specs. Over here in ozz parts will be a prob.

 

I used a fe distributor cap and its working on a 477 engine.

I hate them. Had a 534 for a little while. Then I had to get rid of the thing. It was an awful truck engine.

The 477 I have still runs ok, as long as its started every couple weeks, otherwise I have to take all the plugs out and clean them up, then itll start, as long as it has another vehicle to jump off of.

Of course, this truck weighs 30000lbs, and has 100000 miles, so the engine has done its share of work over the years..

Made in 1974, and still running, so thats saying something.

NO POWER WHAT SO EVER. and the worst fuel mileage of all of my trucks. Most of which are more powerful and heavier when loaded.

 

So you reckon it would make a good moring for a boat

 

Why wouldn't it...it's the same puppy. And...there is no such thing as an FE only dizzy cap.

ALL 1957/74 FoMoCo Passenger Cars, Trucks, Bronco's and Econoline V8's w/single point dizzies used the same: Points, Condenser, Rotor and Dizzy Cap.

Dual point dizzies used a pair of I-6 points, everything else is the same.

 

I think the 401-477-534 were good in their day. Better than the big Internationals, maybe not quite as good as the GMC 478 V-6's. One thing to remember was that the Super Duty V-8's after 1972 or so were way down on power due to emission controls.

 

Ah, I didnt know all the caps were the same. Good thing to know though.

All's I knew was it was for a 390 and I used it on the 477. And it worked.
