hello I'm new whatever...

Looking to swap out the 361 gasser in my dump truck to a diesel either a 6.9-7.3 idi or a cummins 5.9, perhaps a detroit if I stumble across the right one. What I have no idea about is whether or not I can find a transmission or bellhousing to fit either engine. If the tranny in it will work, I'd rather stick with it.

The motor in it is very strong, recently rebuilt, just its a gas pot...

Tranny could use some attention, 2nd gear syncros are pretty much non existent, otherwise its strong.

Overall the truck is in very good condition, aluminium dump, very little rust, drives straight etc.

 

Welcome to FTE.

Figure out what gears you have. A diesel that revs out to 2500 max will be pretty slow in a truck gear for a 3500 rpm motor.

What trans do you have? 5 speed or 4?

Two speed rear axle?

 

2 speed rear, technically a 5 speed but first is just a granny low, only use it for spreading rock and steeep hills

 

Can you post the codes off your data/warranty plate on the door?

If you have an OD trans, and depending on your high range axle ratio, you may be ok with the slower turning engine. Also, what tire are you running?

 

I'll be a few days, its not parked at home..

 

The 6.9 and 7.3 are governed to 3300 rpm rated speed in pickup truck trim, so they would be a good match Some of the Detroit 8.2s were setup for 3000 rpm if I remember correctly. These engines were all designed to fit in a space normally occupied by a large v8 gasoline engine, and to work with variatins of gasoline drivetrains. You may loose a little road speed if your gas engine was rated at 3600 rpm

 

Thanks,

The 7.3-6.9's are basically the same block as a 460, from what I've been told anyway. And a 460 trans will fit, just have to bore some holes out a little.

Right now the top speed is around 50, 55 if I want her to scream a little, no idea what kind of R's she's turning. Work is mostly back roads and highways, Freeway isn't much use to me.

I'll try to get the numbers off it Friday or Saturday, I tend to forget little things after playing with chainsaws and skidders all day though...

 

No no no. The 6.9 is an International engine made in the Navistar factory in Indianapolis. The 460 was a Ford design made in a Ford factory in Ohio. Nothing in common including the bolt pattern, except that they both had 8 cylinders

 

Use a Navistar medium truck motor mount and bellhousing. Common school bus parts will get you started. The medium truck engines were governed to 2800 rpm, so the road speed will drop with the medium truck pump setting

 

So... the numbers are MIA... tag is still there but numbers are all gone.

10.00r20 tires, Had a flat today...

 

> 6.9L & 7.3L are 'cornbinder' (formerly IHC, now known as Navistar) V8 diesels / 460 is a V8 gasser first introduced in 1968 Lincoln's / 6.9L introduced in 1983 F250/350, replaced by the 7.3L in 1988. <
There are TWO different ID 'tags' .. you're looking at the wrong one.

1) Beginning 1970: Safety Standard Certification Label glued to B pillar below the striker plate, has codes printed on it, but...

When it gets wet, the outer plastic layer peels off, taking some/all of the inner printed layer along with it.

But (1970/79) this label only has the VIN, production date and misc weight capacities printed on it.

2) Warranty Plate located (riveted) on the left door face below the latch...this is what you need to look at...as the VIN and codes are stamped on it.

If it's been painted over, you will not be able to know which code is which, so here's the parts catalog example of the little darlin.

Post all the codes from it...
