I went to Walcott, Iowa,to the truck show, coming back i ran 70mph in Iowa and 55-60 mph in IL,IN i got 11mpg bobtailing with 300+,13 speed overdrive,3.87 rears, cruising around 1500-1600rpm didnt think that was to bad. Ron

Rob, Glenn , do you guys have the phone# and the place where you got it. Thanks Ron
-
has anyone tried to put cruise control on a B61, does anyone know of a company that makes them for a big truck, and i wander if you can take one off of a 88-90 chevy pickup truck that is electronic and make it work. Ron

The late 80s R model with airride cab has the exaust bracket that bolts to the frame where the cab crossmember is, you should be able to find a R model with the same bracket, get the serial number and order 2 of them. Ron
-
Trent i never thought about the fuel tank , if you have a 80 gallon tank you might have a hard time routing the left pipe. Ron
-
Is your exaust mounted on the cab or on a bracket to the frame, if i was doing it i would look at some CH613 exaust brackets, i have seen 3-4 differant offset brackets, i bought ( 2) part number 8ME560M brackets to put on my B61, i have a box sleeper on it and have to put the exaust behind the sleeper,they look like they would work on the R model.

Suspension

Show Dog i just got done putting airride under my B, it rides alot better with an empty trailer on but bobtailing it dosent ride any better than camelback except when you hit a big bump, dont know weather it was worth the trouble, money. Ron -
You could check the truck junkyards Mack has been putting airride cabs on R models since 1980-81, might be cheeper if you take it off and get everything you need. Ron
-
Kevin, another thing do you have a radiator that goes down to the bumper, i think the charge air cooler takes a bigger radiator could make your engine over heat. Ron
-
You might look to see if you have enough room in front, it think the charge air cooler hood might be 2-3" longer, maybe someone on the site might know. Ron

I have a 1988 Mack engine tune-up specifications manual, it said intake boost pressure @ rated speed is 15-23 psi for E6-300 4VH, the E6-350 4VH is 20-28 psi

-
I wonder if it has anything to do with vacuum brakes, did they make vacuum over air brakes, it has a fitting that a hose slips on. Ron
-
Where are you going to mount it, i know they go in front of the radiator, are you going to install a bigger radiator to keep the engine cool or mount it somewhere else.
-
Another way to tell is the injector lines go in the head under the exaust manifold on a 4 valve, 2 valve injector is on the top left of the engine.
-
Does it have a wire on top of the valve cover, if it does it is a dynatard , a jake has a spacer plate under the valve cover and the wire comes out of it.

What cubic inch is the 3408 cat.

I have seen F models made in Hayward with aluminum fenders,doors,and the top of cab. Ron -
I have a 72 R model it came with 3.86 rears, i have a 76 and a 77 with 3.87, i was wandering why they stopped making 3.87 and went back to 3.86 , are the 3.86 better than the 3.87. thanks Ron
-
I have a 300+ in mine, i bought an R model top radiator hose at the mack dealer cut it down to fit. Ron
-
That is a long wheelbase, would like to see some photos of it, i bet it is a good looking truck. Ron

I have seen a big 4wheel drive Case tractor that had a V8 Scania engine it had 8 individal heads, dont know weather or not it was stock, looked like it was, looked like a purty stout engine.
