Howdy,
I just had my oil pan let loose completely the other day (rusted through and epoxy broke) and now I have the whole drive train pulled.
While it is all out I'm planning on fixing a bunch of stuff the previous owner destroyed.
The truck was in an accident and it looks and drives like it's fully rolled over the odo, but I doubt it.
Functionally, the motor isn't too bad. It needs injectors, glow plugs, oil cooler, pan, hpop, and an exhaust/turbo overhual.

Build date is 3/98 which means it is an early 99.
I'm rebuilding the tranny and replacing the transfer case as it's completely trashed.
I did the 6637 mod when I bought it and it already had a super chip duct taped in when I got it, though, unplugging it made no difference at all.
It had a vacuum powered bd exhaust brake that was seized up and later I removed the cylinder.
It has some kind of bd transmission controller dohicky that doesn't do anything that I know of(previous owner should never be allowed to touch electric wires).
I am planning on doing the hutch and hatchet (or what ever they are called) mod in the fuel tank.
I'm trying to figure out what all I need to do.
I'm very much confused about the difference between the e99 and l99 motors.
I know there is something different about the pedestal, but can't the l99 pedestal and turbo and up pipes be thrown on an e99 block? Or is there an actual difference in the block?
Since everything fuel and intake related is being replaced anyways, I figure it's about time I give my old man some competition... After borrowing my truck to haul something a year ago, my dad sold his 8.1l gasser and bought a '16 f350. He has a chip, intake, exhaust, fuel lift pump. How much injector and turbo do I need to leave his truck choking in my dust?

Just to clarify, I'm not talking about drag racing him. I'm talking about towing power. We have a large trailer that we pull a dozer and skid steer on. There is one Hill road we go on and it really puts the trucks to the test. My dad's new truck couldn't go any faster than 30mph when he hit the peak. I want to beat that.

I know this is gonna be costly. I'm expecting $9k+.
I noticed there are several different turbo options available. I'm lost as to the difference.
There seems to be a lot of talk about t4 mounting and s366, s369, s467, dieselsite bb turbo, wickedwheel, etc.
The turbo currently on the truck is a Garrett with an a/r of 1.10.

As far as injectors are concerned, I'm seeing 160/30 and 180/stock as recommended for towing. Would anyone be able to confirm that? Would going larger hurt my towing capabilities?

a stock '16 came out of the factory around 440hp and 850 or so ft*lb
Swap a cummins in, that will get some hatters going on here

You got to factor the rest of the drive train in too-
Built 4r100 or upgrade clutch

How heavy are you talking towing? There is quite a difference potentially between a skid steer and d4 dozer lol.

Its been done quite a few times to get into that HP range with a 7.3L... Just search around... Might talk to some running companies to see what the recommend...

The dozer is 17k and skid is 4800. Including trailer it's 36k.

I'm rebuilding the transmission aswell because it's shot. I want to make sure it's gonna hold up well.

This may play to my advantage aswell, my truck is drw and my dad's is srw so I think my axle ratio is a bit higher.

42k is a hell of a lot of rolling weight for a pickup. How much tongue weight are you putting on?

Might look into gear vendors. Even if you make overall more power than your pop, he still can out gear you use the power he's got more effectively. I want to say the 4r100 is still only a 4 speed like the 4EOD, but I could be wrong. The '16 should have a 6speed torque shift....

It's a gooseneck trailer.
Also, I believe I was incorrect. My truck has overdrive and I believe it's not the 4r100.
I'm completely ignorant when it comes to the 6.7. is it the same block as mine? If so, rather than building my tranny stronger, I could possibly mount up the same tranny he has.

Here's the trailer. We had a few poles just in case it wasn't heavy enough. Dozer is 13k and 17k including cement counterweights just behind it. Skid is 4800 including backhoe. I don't know how much the poles weigh, but they werent light. The trailer is 15k I believe, but i could very easily be wrong.

Id say that gooseneck is closer to 8k than 15k unloaded (could be wrong). Still puts you around 30k without the truck potentially.

The 6.7 and 7.3 power strokes are two completely different motors.... As fas as I know, nothing is really interchangeable powertrain wise...
If your truck is an auto, then its got the 4r100 w/ OD.
