Mack E9 Specs


Recommended Posts

I'm new to the forum, I'm 16 years old and from Burlington, Iowa. I've been into the E9 for a while now, it just grew on me, and I've been wondering a few things about it that I can't seem to find. The bore and stroke is the first, for some reason I can't find it anywhere, but someone has to know, I can't imagine a mechanic rebuilding the engine and machining without knowing the bore/stroke ahead of time. Also, what kind of fuel economy can I expect out of it? I plan on getting my CDL after I turn 18 and getting a statewide trucking job, then after 3 years when I'm 21 and legal I'd like to do cross country, I'm thinking independant. Anyway, I just want to know if this is a realistic engine to use, because I'm sure it likes to chug fuel from time to time, but can I expect to do as good with an E9 Superliner or R700 as say (hope you don't mind me mentioning) a Cat 3406 powered W900? Those are the main trucks I've been considering, I just honestly don't know if I can justify using the E9, as we all want big power but there are prices to pay.

this might get me band lol but I like the 3406. I don't care what people tell you you can get good mileage out of them. Deadheading from Dallas to Baltimore at 65 to 70 was 7.4 mpg.this is also with 4.11's. you really do not want to know my loaded mileage right now it is in the basement. best I've gotten loaded is 3.5. Mind you I am heavy haul. and have a 379. Idk much about Macks but I know that it is all how you drive it. E-9 is a monster and will drag anything you put behind it. What are you planning to haul. if your going to pull a bucket then get the Mack. Lowboy local, Mack. But if your gonna run the state side to side top to bottom. I like the W-9 more for comfort or get an Air ride Mack. I like My Pete but would of liked to have gotten a Mack. if you go the Cat route stay away from anything late 03 to well anything after that. my 98 has the power I want. and no pun intended will walk the dog.

E 9 is an awesome engine. What I have found over the years running them is they are a one man engine, don't run them hot, so watch your pyrometer and your temp. It is easy to get in the red. I found in the extreme hills of Vt. running thermostats lower than 180 degrees works for me and they are very expensive to rebuild. Fuel mileage with 4.64 rears loaed is 3 and empty 5 to 6 for me. The first V 8 I drove was a 440 in a superliner with the twelve speed back in 1983 and have been hooked since. Love that sound and power.

Phildirt, thanks for the info. Right to the point.

Slpwlker, I also like the 3406, but I wasn't questioning that you can get mileage out of them. They may not win any awards, but it's usually better than any V8 diesel. I like the 3408, too, but my biggest concern there is it being a 60 degree V8, and the cracking problems with the crank. I just love the E9 because it's a good, sturdy, old fashioned 90 degree V8, and you got some pretty big cubes. It's about 100 CI short, but that shouldn't be a problem. As for the lease, my plan is to save my pennies when I do the statewide stuff, and hopefully after 3 years I can afford a good dog from Truckpaper.

Timothy, thanks for the info on the temp. I love the sound and power, too, and 3 isn't too bad loaded. Hopefully I could do a little better by throwing something in the 3:1 range in the back and running an 18 speed.

Superdog, thanks for the welcome, good to be here. Glad to see we're both from Iowa, too.

I would maybe go up to a 4.17. with the right trans you'll have good low end and that thing will run like a raped ape. There use to b an 84 Superliner for sale in Orlando,Fl area had extra doors. Price kept coming up out of my range. Had a 350 Mack and 13dbl over. Never looked at it. Reason I was looking was gonna start teaming with the Fiance and I couldn't do it in my current set up. Landstar wouldn't let us because I had to many axles. had to pull a flat or step and Wanted that or a Cabover.

Remember when the biggest engine out there was a 425 cat? Even the 12 litre Mack 350 did more for it's size. Pulled a 50 ton low bed for years with a 350 and 12 speed and got the job done with no problem. Then the industry pushed for bigger litre engines. For over the road I wouldn't hesitate to redo a R model from the "80"s and save yourselve some money in the long run like on all the electronic B.S. that is out there. The only thing is, would these old style engines pass our different emissions from state to state?

I agree. I've never worked on a semi before, but I've worked on plenty of cars with my dad, and the two easiest in my book are his '73 Mercury (429 big block powered) and his '78 Econoline (460 big block powered). It seems that when a company goes for less technology and more cubes to get the job done, the engine is generally easier to work on. That '78 Econoline is my daily driver, too. I'm hoping driving a 15 passenger van will get me a little bit more aquainted with driving these 18 wheeled beasts.

Everyone else, thanks for the input and advice, it helps a lot. I got another question to throw on the list, too. Do you figure an E9 would fit between the fenders of a B61? Those trucks are just beautiful, and it would be a nice truck to drive. And if I can get B61 looks with the power of an E9, I'd practically have my dream truck.

That would an awesome combo but not sure if they would mate together and a B model isn't the most comfortable for a daily driver. Great show truck though!

Yeah, I think it would be an awesome combo, too, but what exactly makes it uncomfortable? Is it the ride, the interior, or what? Because if it's the ride, it could go to air suspension. I know that's not an easy swap, but the E9 wouldn't be either. It would just make one mean truck!

Small cab for some. I've had one and loved it but wouldn't want to drive it everyday. R cabs aren't very big either but more room. First CH I drove, I liked how much room it had but still liked the R series better.

I guessed that may have been it, the B61 doesn't look huge. But if the R series aren't too big, it can't be that bad, because so many people drive R's. Obviously a Superliner would be more practical. I also really like the older cabovers, but I'm not very familiar with the models.

Sounds like you'd be somewhere around Morning Sun if you're 20 miles North. That is if we're talking about Highway 61.

This might be a stupid question being from Iowa,have you been Iowa 80 walcott truckers jamboree if you havent it is one you shouldnt miss great show. Ron

Kid, Looks like you hit the Jackpot, with Mike only 20 minutes up the road. I'd be up there on weekends volunteering to do anything he needed done on his trucks.

Maybe, but that takes gas money. I get 7 mpg in my van, so that's something I don't have a whole lot of. Not to mention I don't have a job anymore. I've had two, but right now I've got nothing. But one of my friends offered to put $20 in my tank just to hear the 460 run and get a ride in it, so after I've got the brake line replaced (when it warms up), and the starter too, I might go take a look at those trucks. My friend likes Macks, too, I'm sure he wouldn't mind.
