My 7.3 engine build

[Oledirtypearl86]

So I've had a slight back burner project going and finally decided to get a bit of input on it that being said this is what I'm after
I want reliability first and foremost. enough power to pull 20k in the mountains and not get run over also an overdrive so I can go faster than 55 mph
What I have a 1986 f350 idi with a 6.9 and a t19 trans also I have a hypermax turbo kit on it
The build
I have a 7.3 low miles
Several turbo options and a gear vendor that needs rebuild
My plans are to rebuild the 7.3 and studd the heads then build a kit to install a h1c and intercool and top it off with a built IP from Wes iv also been thinking about a spray of water **** to cool things a bit then put the vendor behind it all if I can't get a zf5 am I missing anything

I picked thease 2 turbos up for 200 the bigger is good no shaft playand I seen Run the smaller needs a rebuild has a tiny bit of shaft play the super small snail shell is of my wife's Jetta pic was taken to show size for wife lol

What do you have now for gear ratio? My 93 2x dually has 4.10 , factory turbo, ZF close ratio trans, factory size tires. Can easy run down the road 75, get 15 empty. My equipment trailer loaded am pulling 18-20 k . granted on the hills we have it pulls down on a long pull, but on level pulls as fast as I want. Hope you project works out good for you.

I have 4.10s and am running 33 inch tires been looking for some 3.73s but that's later down the road and the truck right now runs great I can pull homestake pass in 4th the whole way to Butte with my 9k camptrailer but I'm looking for more power an hopefully a bit more fuel mileage

 

[Randy Bush]

what is your top end right now and mileage now? You might regret the 3.73s I would go with the overdrive or ZF first if it was me.

 

[Oledirtypearl86]

Right now my mileage is mid 14 and not to sure on top end but as my tach is a bit on the fritz but she is wound pretty tight at 65

Also I agree I would like a Zf5 more than gearing I could get .Zf6 but not sire what it would take to mount to a idi

If you get a ZF5 get the close ratio one for pulling that kind of weight. Had the wide ratio in mine and it was no good for pulling what I do. Have no experience on the ZF6 .

My understanding is that the ZF6 isn't worth the trouble unless you have one already. The only difference as far as I know is there is another gear in the spread so you lose less RPM between shifts. It's not a double overdrive.

ZF5 on the other hand bolts right in and gives you overdrive so that one's a no brainier.

the gear vendor AND a WIde ratio zf5 would work pretty good. And 4.10 gear

 

[Oledirtypearl86]

Does anyone have any idea about the gear vendor like rebuilds they seem to be pretty hush hush as far as parts for them but have herd thay the clutches in them are the same as a turbo 400

What does the gear vender have direct and over or an under to.

When I first got my 93 dually it had the wide ratio, was great on the road empty, but for what I pull loaded, 18 to 20k it was no good. Rebuilt the trans and made it a close ratio , pulls great now and run down the road 75 easy ,has 4.10 too.

Using the gv to split the wide ratios works good, and unloaded double OD would be real nice.
