Hey, I'm working on a 421 with the gas engine. Right now it has the original steel gas tank. I have two aluminum saddle tanks i was thinking about putting on it instead of the steel. what I was wondering was, would those tanks be OK to use with gas, or is there any laws that say you have to have steel tanks? Thanks in advance, Daniel

I'm planning on doing the same to my B-421 and would like to know as well. Thank, Josh.

most of the en401's and en402's had the option of an oil cooler. only main difference was 2 more added head bolts on the en402's on the outside left corners, front and back. as someone else said, barely enough power to drive a truck around empty let alone loaded, and if you got 80,000 miles out of one, you were doing good. ~Matt

In 1971 somebody solved the no power problem in my 1959 B-421. They took out the EN-401 and replaced it with an EN-414[AKA Chrysler 413 industrial V8], which means more power and less gas mileage , Josh.

Here's the other 2. Does any one know if the blue on is still in Pittsburgh and if so were in Pittsburgh is it?

I'm curious as to how many B models were made with the fiberglass tilt hood like the one below. If you ask me in the front it looks alot like a Superliner 1. I would love to find one of these or at least just the hood. Does any body on here have one? I have pictures of three of them. One of which was a blue dump truck in Pittsburg, Pa[i wonder if it's still there ].

Thanks, Josh.

I can't find the serial number on my EE parts truck. There's no cab or engine so yould think I could find it on the frame. Please help. The only thing I could think was that I'm not looking in the right place or it was never stamped.It's farely old for an E model because it has a cast iron rear cab mount rather than two rubbers. I don't have the serial number tag so I relying on the frame being stamped.

Thanks for any help, Josh.

How about this one ... it was on Ebay last year. I pesonally like it better.

Thanks, Josh.

I'm just curious as to how many of you are going to ATCA show in Macungie, Pa? Aren't they featuring trucks this year? Who ever is going take LOTS and LOTS of pictures ! I myself won't be there. Also if there happens to be any Magnums there please take some good photos and try and get the serial numbers to go with them . ALSO to all that are going have a great time!!

Thanks, Josh. !!!

thunderdog, I can't wait to see it all done . Looking good so far.

Vision 386, I completely agree with you.

My brother and I might be soon getting 2 ready to paint ourselves . Our B model and a Magnum , but the Magnum isn't ours though .

I found the following in my book;

Prince George Mack Sales and Service - Prince George, BC

Mack Maratime LTD - Bathurst; Fredericton; and Moncton, New Brunswick.

Thats all the more my book shows for what is still left of the list. Hope it helps.

Thanks, Josh.

I'm curious as to how many WS722 Cruiseliners were made. They were powered by Mack E9440 V8s. I'm curious because a local company had one and they must have scrapped it this winter . I just found out today when I went to get the serial number off it. I would have liked to have had it but I guess that isn't going to happen now . Keberts in Meadville PA is the company that had it.

Thanks, Josh.

Does any one on here have pictures of the Superliner Magnum that Roger Gerhart had? I have only one picture of it and you can only see the side of the hood.

Thanks, Josh.

Superdog-

Can't help on the that- the databases are limited to Superliner and Ultraliner Magnums.

Will,

I talked to my dad the other day and he said when my cousin Micheal bought 1705 the engine was blown up [the E9450] so there's the difference in the engine. When I've seen it, it has always had the replacement engine [the E9500].

Thanks, Josh.

Also need some nice Magnum stripes but scaled down to 1:13.

I'm working on a 1:25 scale Superliner Magnum and I found a place that has a 1:25 scale set on Magnum Decals for $3.50. They might be a little small for 1:13 scale though, but I also have a set on the computer that I made that are a little too big for 1:25 scale so they might work for you.

Thanks, Josh.

John'

That's deffinently the engine . 1976 would deffinently make it PRE E9 and means it was made when they still made the 865 and 866. COOL !!! The intake is just what I thought it would look like. Thanks for sharing the photos with everybody. Does any one have a serial number type of the R-700s that had the ENDT1005 for example R-795 had the ENDT865 and the R-797 had the ENDT866 so what R-7?? had the ENDT1005?

Thanks again, Josh.

Will,

Thanks for the info on 1705.

Superdog,

Do you have an pictures of you Freedom series RW613 Superliner? Whats she got for an engine? I didn't know there were any Mack Magnum branded goodyear tires. There probably aren't to many still out there.

Thanks, Josh.

Looks to be in pretty good shape. I've heard the Mack EN414 [AKA Chrysler 413 indutrial] is suposed to be really good motor. The Mack B-421 that my brother and I have was repowered by one in 1971. Ours needed rebuilt because of a bent rod so we havent had ours running yet. How some engine pictures of your MB. It looks like a nice little truck that should do the job.

Thanks, Josh.

Sorry, I'm little confused by that post. Thanks, Josh.

Thanks for the info on the Superliner. Can't wait to see the Magnum all fixed up. By the way whats the vin number on your Magnum. Keep them comming. Thanks, Josh.

Watt's Mack Sales ordered 2 Magnum Superliners on 11/26/1984. The salesman was J. P. Watt. The two trucks (chassis # 001325 and 001326) came out of Hagerstown to assembly about 04/02/1985.

See the attached .pdf for details of the trucks as ordered.

Will,

The one that was my cousins that Ted Crea has now is chassis number 001705 and was

supposedly sold at Watts when it was new. It has a 36 inch Able body Bunk that it was built

with from the factory, an E9500 engine, 38000 rears with power divider lockout, single 5/16 frame [NOT double frame], and had a T2090 9 speed tranny but my cousin Micheal[the one who had it] put in a 12 speed tranny. Here some pictures of it. What does your info show about it?

Barry,

I would still be interested about the other two Magnums sold at Watts.

Thanks, Josh.

Just refreshing. Thanks, Josh.

Just refreshing the post. Bring on the Magnums. Thanks, Josh.

Barry,

I would like some pictures of them most of all if there is any. A friend of mine is doing research on the

Magnums and has a copy of the build sheets to all the Magnums and I'm supposed to get a copy. I would just like to have a picture or two of the ones sold there at Watts to go with the build sheets.

Thanks,Josh

Barry,

I'm looking for any info on the 2 1985 Mack Superliner Magnums that were sold at Watts.

At one point one of them was owned by my cousin Micheal Huppenthal up until several years ago when Ted Crea bought it. It had a 36 inch Able body bunk on it. Also is there any pictures of these two truck when they were new? I'm very interested in the Magnums so I would be greatful for any info or pictures you could provide.

Thanks, Josh Yoos.

John,

I received the email but the email blocked the photos and said they were unsafe. I've never had this

problem before and I'm not rely sure what went wrong. Can you try and send them again. Mabey it's because they were

PDF files ? Could you change them from PDF to something else? I have been having PDF file problems lately.

Thanks, Josh.

The Mack V8 you mentioned with the twin turbos was an ENDT864 V8. The R700 it was in would have

been was a R719. At the time Mack had two V8s the END864 [non turbo] and the ENDT864 [twin turbo].

The twin turboed 864s are very rare and are hard to find because they made so few. These were

the predecesors to the ENDT865 and ENDT866 both of which were single turbo charged. I might be

a little off on the ENDT864 sequence because they made some with different horsepower ratings

, but I'm pretty positive the ENDT864 was the twin turboed one [T standing for turbo]. As I said

before though the 864s were only made as non turbo or twin turbos and they were the only Mack

V8 to ever be made with twin turbos. That should pretty well explain about Mack twin turboed V8.

Thanks, Josh.
