Hello,
I have a 1982 F350, motor is D7TE-A3B 351M400 with
T-18 trans 13-01-065-907 BorgWarner
and an 11" clutch and pressure plate
c= D935 3606 pp=AMC 23.
I want to put a 429 D9TE-AB into this truck.
The truck is standard but the 429 is from an automatic.
The 429 is externally balanced while the 351M400 was internally
balanced.
I don't have the casting number for the bellhousing but could get it
if needed.
What do I need to replace - and with what - to make this motor
work in this truck?
starter? Bellhousing? flywheel? Clutch and Pressure Plate? Motor Mounts?
any help would be greatly appreciated.

If that 429 is a D9, its a 79, they quit making the car 429s in 72, what you have is a heavy duty truck 429. It makes a lot of torque, but its extremely limited RPM wise. It also has really low compression (7.2:1 I believe).

I doubt that it will bolt to your existing transmission.

The 351M that you have is externally balanced as well.

 

Thanks, I figured out the 351 was external too. Now help me understand the difference between a car 429 and a truck 429. What did the 429 come in and what tranny did they bolt to it?
The vehicle is a one ton dump truck, would the low rpm make a difference in this application? Also, could I use this motor by changing transmission too? and if so, to what?

The 429 was hooked up to mostly C-6 when used on automatics. Since it's a big block engine it won't mate to the smaller blocks. Change the bell housing on the T-18.
I didn't think the engines were ever made with C/R's under 8.0:1....

If I were you I'd look for a later production 460 which is more suited for street vehicle and light trucks. Up to 1985 or 86 they were carbureted and were light on electronics.

The 429's an awesome engine, but what you have will require pistons, heads and cam to make it a good streetable truck engine. It will cost more to do than to drop in a good street-ready 460.

 

Uh, guys, the 351M/400, 429, 460's all use the big pattern bell housing and all use C6 automatics. Only exception is some car 400's that were cast with small pattern bells.

 

DANG it! I knew someone would say that! I just happened to have had that one 400 that was smaller and FMX!!!

 

I do know that this 429 will bolt up to the bellhousing that i currently have,
what I needed to know is what flywheel would fit this set up and what starter.

I've messed around with a lot of swaps and have a 429 and a 400 sitting in my shop right now, but I haven't actually swapped one for the other - so, I'd just head to the local junk yard and find a flywheel and starter for a '79ish 429/460.

Or take your flywheel from the 400 to the junk yard to compare it to a 460. I don't have a 460 fw loose to compare with. But as long as the balance is the same and is drilled for an 11" clutch...... where's Barry when we need him? (he hangs out in the 48-60 forum and is an old Ford dealer parts man with all the books)

You may find the starters are the same - might try using the one you have first.

Also I've heard conflicting reports about motor mounts. Let us know what you find.
Sorry I can't be more helpful.

 

the starters are the same.

the flywheels are the same as well.

I really don't recommend putting this 429 in your truck. Its not made to rev at highway type speeds. It was a heavy truck engine, with very low compression.

 

The 400 and 429/460 flywheels do not interchange. They have distinctly different crank patterns although the clutch pattern is the same on manuals. The 460 and FE have the same crank pattern but you cannot use the auto flexplate from an FE on the 460 due to the larger diameter. You can use the 390 manual flywheel on an internally balanced 460 with the 390 pressure plate. Also from your casting number I do not think you have a 429. As I understand it , the last year of production for the 429 was '72 but even then If it is, the bolt pattern would be the same as the 460.

 

The last car 429s were built in 72, but they built the Truck 429s all the way to 86.

 

Hey all, thanks for the input, I'm just gonna drop a 390 in this thing and be done with it. Trading the 429 for a 390 with tranny and all in between. Thanks again.

I have a 78 Ford F150 that has a 400 in it, well the 400 bent a push rod, and one of the cylinder walls have deep scratches from getting some type of alluminum in it. I bought a 460, that runs, just going to replace the gaskets and then try to drop it in. I have been looking around for motor mounts but cant find any. Can anyone help? Also I have measured the gap between the bolt holes off of both motors and they seem to be even, it should be alright, right?

 

I replaced a tired 351m in my 78F150 with a 460 from a similar year van and both were automatics. Straightforward swap except for frame stands. Needed some from a F250 wth factory 460. Everywhere I went they were already taken. I ended up making my own which worked out ok. I used the same radiator although looking at factory F250 w 460 the radiator was larger.
Both vehicles were 2wd, but I'm not sure if the van oil pan is same or not, but it worked in my truck although the dipstick was about 5 ft long!
