    With my pump turned up I could walk a friends 427 up to about the top of 3rd. Hold the lead thru 4th and only when I grabbed 5th could he get around me. It just don't have the balls to keep up in 5th but were talking a 1977 diesel vs a 2001. Not bad for the old dog...

    Still need to know the final drive of the transmission. You likely have a 300hp diesel with 1:1 final drive. If that's true a 4.17 rear would give you about 62mph at 2300.if that's to slow a 3.87 would give you about 68mph if it's to fast a 5.02 would give you around 55mph and more low end grunt. Some of the other fire truck guys should advise as I just ran dump trucks...

    When I had my RS700L on the road working I bumped up the pump so that it pushed about 28PSI in summertime warm weather. If I recall I turned the nut to adjust fuel about 2-3 turns and locked it back down. it reaches about 30psi in the right cold weather. I was getting about 5.2 - 5.4MPG running chicagoland. she smoked a little more betwee shifts and I have the pufflimiter operated from a dash switch. EGTs get a little warm on a good pull if its falling below 1400RPM. I think +25% is a little hot but if you are driving the truck and watch the gauges you will do fine. Many shops wont do that much and give you a warranty on it tho....

    would have to agree Al. if you had basic wrenches,some large sockets a braker bar and duct tape you could just about fix or remove and replace anything on those engines.

    if you turn the stock pump all the way up you would be pulling wheelies. thats what our sled pull truck has done and the throttel is like a light switch. if its a working truck bump it up 20-25% and call it a day. you will have a notice of power increase.

    He put a new cab on The valueliner 3-4 years back. Bought a complete new Cab fron N.I.M with basic the interior. heard it was one of the few R cabs mack had left in stock. I bought his old western interior before he scrapped his old rusted cab. Truck has a 300+ think a 13 speed with camelback spoke rears, solid mount cab.

    All are still working and took pics of them 2 weeks ago... The last pic of the rd was taken 6 years ago. It is a glider kit. 2v 300-6spd. Great truck. The gray truck is a ford l9000. the owner is who gave me my start in a r model. . He now has a ch,Pete, and fords.

    just a thought... Is your coolant level low? if it is water might not be able to get to the heater core being that it is one of the highest points the coolant flows to... if its topped off it has to be a bad valve or blockage. does that water pump have a nipple on it that is capped off or is there another nipple you can plumb into?. you might be able to run a hose right off the pump and see if that corrects the heat?

    low temp in one hole can be many things. Bad valves, low compression,bad injector, anything that will not allow that hole to fire as strong as the others.

    That's the world record diesel 1/4 mile run. One of the fabricators at my work was involved in this project. You can see him in the video. I want to say its based off a dt466

    First find out what rear ratio you have. Or let us know what trans you have and we can suggest a ratio.. There were a lot of options but some will not work well depending on your transmission. Did you want more hi way speed or were you happy with the current top end?

    If the shaft hits the housing then it's worn or broken bushing and seals shot. Find a new turbo before it snaps the shaft,runs away on the oil, leaves you stranded,or all of the above..black smoke is likely that you have no boost. The puff limiter needs to see about 15psi if I remember correctly to give full fuel. The limiter just delays delivery. Once it's spooled up and above 15psi your foot controls the fuel amount. If you can't build more than 15 psi or the puff is unhooked it will be dumping to much fuel with to little boost. That's where the black comes from. As for white that can be oil or poorly burned fuel.

    I think Mack out sourced all sleeper installs . My truck had a crawl in 36" bunk. They just screwed the boot right to the rear wall of the cab around the windows frame. When. Bought the truck the sleeper was removed. Luckily it was done well as I was able to weld those holes up and sand it smooth. Now I want to install the sleeper and don't want to put holes back in it...

    Normaly it's just 3 points of contact. The bell housing has one each side and the front of engine has one. This allows the frame to twist and not brake mounts or the block,trans case etc...

    ok so what kind of destruction did a 7 ton projectile do? Was it just a slug or did it have some kind of explosive attached to it. i would have to think it would go thru about 10 buildings if it had the right angle but they all seam to be aimed at the sky, that tells me it was likely coming back down at a steep angle?? intresting stuff

    When you say bent is it worn to the point that it can touch the housing or do you just feel a little free play? can you tell id any oil is leaking out the exhaust side or intake side? I put a turbo on my truck from a junk blown engine . cost me less than $50. lots of the old engines just sitting around. hard part is finding one that was not kept out in the rain with the boot off the turbo so water did not get in.

    thats actualy a good idea Vlad! would have never guessed that.. I just dont want to drill into my cab. its almost 35 years old and is in great shape.

    Thanks for that list. those are popular mack transmissions Did you happen to add up the Quad and 6 speed? those were pretty popular as well. Still have to have my 12 speed installed so I can get to and from the show a little faster!

    Yep has a Cat motor in it. It was for sale last year and I looked at it. nice truck, had a little rust in normal spots and the alum frame was cut and welded at one point.
