  1. Dale Francis (440-254-4046) is very knowledgeable on these V-8's. He is in Leroy, Ohio. Crank shafts are not cheap or going through the motor, but he should be able to give you a close number on what it would cost. Reman heads for these motors are $1,600.00 each from Mack, X's 4. Rebuilding the injection pump could go into the thousands, heard numbers like $5,000.00 if they need hard parts. You could put $20.000 into a motor pretty quick. If you search you-tube or the web, you can find video of his shop. I'm sure there is other maybe closer to you also.

  2. I just went through this with a friends 06 Granite, put super flow injectors in the truck would not fire, ether was the only thing that got it going. Not crazy about using it on a every day use but sometimes you do what you got to do. A little trick is to open the passenger door and spray into the air cleaner through the crack in the door opening, better than running around the truck.

  3. I got my antique plate for my B-model yesterday so I could at least drive my truck once in a while when I get a spare minute or two (LOL). Only cost $133.00.

    Anyway, now the problem I have is the one I'm driving is a 422 that was converted over to a diesel with a two stick 9 spd. The rears were never changed, so the ratio is 7.00. Need

    less too say, the truck tops out at 45 mph. I have a quad box to put in or should I look into changing the rears? What ratio would work best if I leave the 9 spd. in? Truck has 10.00 X20's.

  4. Yes there is a power divider there. It does not have air controls on that one, your truck was probable built with an air shifted divider but the rear was changed at one time and the unit they put in has a standard power divider. The way they work is if you have a tire spinning, spike the brakes while it is slipping and it should through the power to a different wheel. An air shifted one you would just flip the switch to lock the divider in. Never seen a rear without a power divider.

  5. Well that's what I was thinking, and thinking always gets me in trouble, was going to run it in my excavators and backhoe to help with fuel costs and if I had problems, at least they would be off road. Probably have to pack an extra lunch with the smell of fried food on every job site. LOL :whistling:
