If I keep a 1:1 tranny, what's the useable RPM range? Is it going to tear it up screaming down the interstate at 3K rpm every day?

Fuel mileage will suffer, big time at that RPM.
Your wallet will suffer much more than the engine will, even at 3300 RPM all day.

1000 to 3300 RPM.....in something as small as a Bronco, the 750 to 3300 RPM range will all be useable.

You have 4.10s still or have you changed them. I believe I would swap to a 3.55 gear at least. They should be easy to find. The Ford 9", that you have, shouldn't be to hard to find in 3.55.

Well 10 years ago it wouldn't have been but times have changed and scrap metal has been up.

I've got the stock 3.50LS gears. It's a bit of turd now with the 35" tires, but I see them being a good thing with the diesel torque. Prolly help those highway revs too.

What about an AOD...no compter needed. Was there ever one behind an IDI. If there was, how to mount the kickdown lever?

No AOD behind the diesel, E4OD was the only overdrive automatic.

Steve. When you built the motor mounts, did you move them back any for better weight distribution, or line them up with the factory mounts?
no on my truck i had to move everything forward to clear the firewall

TCS Detailed Product Description - Baumann Electronic Controls, LLC Heres a link to the controller David 85 has. Its a pretty cool unit. You can custom tune almost every aspect of it. And they are about the same price a stock TCU. They also offer a shift kit that combined with this lets you make the trans shift exactly how you want.

As for hou they are controlled. You will need a FLPS fule lever position sensor hooks on the side of the IP basicly its a TPS, Then a tach signal and a speed signal wich both have to be very acurate. and of coures the wiring from the trans.

You will definately want to make some internal mods to the trans befor you put it in. If you have the funds I would rebuild the whole thing.

Stock fan, or electrics? Which radiator did you use? I notice your blower box is missing. Did you have to remove it to fit the 7.3, or was it already gone?

Thanks for the input George, the E-tranny will probably have to wait. C6 rebuild kits are cheap.

my truck was a non a/c truck so it did'nt have one.i used the stock fan,the radiator is a 4 row from a 90's truck that a buddy gave me.i had to clearance the core support to get it in.it is not as wide as the one from the donor truck but it is a crossflow so it may be good enough?has been so far.i also set the motor above the front crossmember so i could keep the 7.3 power steering pump braket.

Does the IDI have a belt driven vacuum pump? Does it run the brake booster directly or is there a reservoir?

Or is it a hydroboost brake system?

Belt driven vacume pump. I want to say it runs straight to the booster but I think its gotta have a resivor now you got me woundering I'll have to go look. Also you could run hydroboost off of one if you wanted to.

Aperantly theres no resivor the line runs from the pump to a 2"x1"x5" vacume manifold and then to the booster.

My 84 had a resovoir with a small vacuum line going to it, but I took it off and plugged the line to make room for my heated fuel filter, still stops fine. Cookie, when you get finished or close can I come look, I'm thinking of doing the same thing with my 76, it blew the motor this summer, and I bought an old 86 Diesel at the auction running but the truck was rough as could be for $400, by the way if you want a 4 spd manual I got one right here in Lonoke.

A resovoir will give you more braking power or a vacuum reserve so you can make more brake applications while at low RPM's.

I am running a hydraboost system off a 97 Super Duty, bolt on fit, on my 86.
Now I have real brakes.
The hydraboost actually takes up less room, but more hoses than the vacuum booster does.
