Thus the engine is more efficient, the better gas mileage and the MPH pick up is there.
Tell us more about this wonder oil...

I talked to an auctioneer that used Slick 50 as an oil change years ago. He said he was doing an auction with hundreds of cases of Slick 50. The auctioneer had some workers change the oil, transmission fluid (4 spd) and the differential oil in his old truck. That was a '59 F-100 1/2 ton pickup and it got 32 mpg on the highway. I bought that truck from him and it got 24 mpg hauling a cord of firewood. He claimed it was because of the Slick 50 based on when the high gas mileage started.

That's not necessarily a good example because nobody in their right mind would use straight Slick 50. I ran regular oil in that same truck for several years and continued getting the same high gas mileage. Eventually I had the engine rebuilt and it still got the same high gas mileage. No explanation.

My fuel pincher engine specs read
Idle min. RPM 700
Max no load rpm 3050 (don't know if that includes chassis and body or on a stand)
170hp at 3000rpm.

Sorry
Just catching up to kubla from yesterday and just found everything I missed.
For the mystery oil man.
These old 8.2's we are talking about are non turbo so no boost there.
I also have an old 77 ford that I have been debating changing to synthetics in but I hear a lot of debate about upgrading to a newer synthetic oil for older engines and the biggest thing in a lot of the mystery oils is a zinc additive that fills in the voids in the wore out parts like bearings and cylinder walls but also start collecting and filling upthe oil passage and pump strainer and other things.
I assume you have heard some of that also?

Definitely doing taller tires and would like 4.44 gears for speed. but am still in a debate in my head if those are the right ones for me?
I will sacrifice some top end speed to be able to tow a trailer with car or 4-down and still be able to do 55-60 while leaving my 8.2 at its factory settings,adding a cooler to my 545.
Maybe my solution is changing the tranny to one with an overdrive and keep my 6.50 rear (with some TLC of course).
For any newbies following please do your research and buy the power train already in the bus that fits your needs cause no matter how much you put into your conversion the power train is what makes it move and the power train combo decides how fast you get there. How much weight you can tow and or carry.
I love my bus. I didn't get any drive time before purchase. All I got was visual.
But buying from a school system that owned the bus since brand new. I did get full maintenance records,manufacturers build sheets and wiring diagrams for the ford chassis and Thomas body.
Good luck

going overdirve will be a pricey or an involved adventure on a bus that age.. the OD automatics are electronic, or you can go manual and install a clutch and all to get OD.

I love a stick shift and would really love a road ranger tranny.
I can dream can't I?
I will make what I have work enough to make me happy.
For me I don't want to change the governor and kill my engine or tranny in a year of hitting the road to freedom.

Take a few shims out to allow the top speed to be increased

I'm not trying to be insulting in any way, but I hope you know what you're doing doing. Changing the governor is a job that a lot of mechanics won't mess with.

Having worked as a mechanic in the past, I was never allowed to change a governor.
