Ranger Split -Gear Overdrive Unit f250/Buick
Ok, this may sound strange but I'm building a 87 ford 6.9 with chopped frame on which I will mount a 1930 Buick body. Since this 4 speed is going to be a daily fun driver I'm wondering about the advantage/disadvantage of adding a Ranger overdrive unit to increase my topend. I also want to add a limited slip to my 3:55 differential. Comments, questions and advise is solicited since I've got the time now to play with this creation. Oh, yea..its also gonna have a WVO tank..

I haven't picked the tire size yet. Since it is primarily going to be a daily driver I'm thinking 17-20 inch tires mounted on alloy wheels. Not overly wide, probably narrow to replicate what a 30 Buick tire would resemble. I am open, however, to suggestions since this is an agressive first time project for me.

Make sure you have a way to heat your WVO. Also I hope you're using two tanks, one for diesel when you start and then a way to switch to your WVO when the engine is fully warmed up and then switch back to diesel when shutting down. Starting up cold on cold WVO is a good way to coke up your engine and put an end to your hobby.
I've been running a Mercedes with two tanks and a heater for almost seven years now. I love giving the oil companies the finger every time I drive my car.

I'd definitely hold off on doing anything with the final drive ratio until you pick your tire size. That will give you more accurate info on what your RPM's will be at a given speed.
Gear Ratio Calculator
Pretty neat calculator that will let you try out different combinations before you decide.
Sounds like a cool project!
