Hello guys, i know that e9 has around 390 retarding horsepower at 2300 rpm, but how safe is to go to that rpm? Do you have some expirience with dynatard on e9 at more than 2000 rpm?

Very interesting artical Paul....Maybe Aussie operators prefered the steel hoods thinkin the fiberglass hoods wouldnt stand up to being hit by a Roo or Wombat....just a thought. Paul

Copied from Mack Muster Facelessbook page 🚛 This Week’s Fact, Countdown to the Mack Muster, 21–22 March 2026! As we gear up for the Mack Muster next March, here’s a look back at a key moment in Aussie Mack history. The very first two Australian R series field-evaluation units, the lighter-specced R403RS and the more premium R609RS, rolled out sharing the same fresh appearance, brand-new chassis and a noticeably larger cab. But their stand-out feature was something truly ahead of its time: a revolutionary one-piece fibreglass tilt bonnet. This new fibreglass design made engine access far easier than ever before. However, many long-time Mack customers were still big fans of the proven heavy-duty steel-sheeted bonnet and fender setup, similar to the B series. With such strong feedback from operators, MTA engineers soon introduced a steel-bonnet option for the R series. This rugged, tough-looking version quickly earned the nickname “Flintstone” thanks to its (stone age) strong appearance. More history, more trucks, and more stories just like this will be on show at the Mack Muster, 21–22 March 2026. Don’t miss it! 🚚💨

Is there a conversion set up on the market to retrofit spring brake chambers to the rear drive axles of my 55 Mack LJSWX, or do I have to fabricate my own set up?

Back when Automakers actually cared about what Customers wanted instead of just making money. I know that 400M backed by the C6 transmission in my 79 Bronco Could move that 3 ton beast pretty good especially when the other 2 barrels on that Holley 650 kicked in!!

Thanks for passing this along. Good parts list here: Maine is a world away though

Clevleland was the first of the 335 family. Back in the late '60s when Ford came out with the 460 someone from Ford looked at a Big Block Chevy's canted valve arrangement and said "hmmm.... we need something like that" So they made the 460 and 429. They were called the 385 family. Oh, and they were coo coo powerful just how they came in the land yatchts they came in (Lincoln Mark 3s 365 HP/500lb/ft torque and the 429 Thunderjet wasn't too far behind 360/480) Then there were a handful of high performance 429s . Then they decided to use the same arrangement in a smaller engine. The 351 Cleveland. The first ones were pretty strong and responded to being hot rodded. They were sorta short lived though because of strickter emission requirements. By that time, The FE family (352s, 360s 390s 406s 427s and the 428) were all gone. The 351M was still a 335 (as well as The 400M) and kinda filled the void of the 360s in the light trucks. The old 289s, 302s and 351 Windsors were all based on the same platform. The 302 and 351 Windsor seemed to hold on a while in pickups and passenger vehicles. Ford must have spent a fortune retooling over the years, they had lots of different engines , many for the same applications too.

Got a picture in the mail today, the official photo from the Trucker's Parade Against Cancer. The Mack doesn't look half bad there. We didn't have our banner on it when they took the picture because we wern't sure we'd even be there, so they put it on a fire truck. We were supposed to go to Raphine that day and pick the yellow '55 Ford up, but the man bringing it broke down in Jackson, Ohio so he turned around and went back to Indiana. My wife informed me that we had an official picture from last year, but I don't recall ever seeing it before.

Go with your line theroy and see how it goes !

Fords are weird. The '71 F100 I had had a 351 in it, not original, but it was smaller looking than this 351M, it looked the same as a 289 or 302. So you've got a 351 Cleveland, 351 Windsor, 351M, and some trucks had a 352, and they've got the 428 and 429 engines which were different animals too...I guess. I always thought the Cleveland was the one to have if you wanted to go fast. But when I was coming up most everybody was racing either GMs or Mopars, very few fast Fords around on the street.

Nothing of mine, just something seen on Faceplant! https://www.facebook.com/marketplace/item/2860163514175279 .....Hippy

Ok thats great, I'll mesure them tonight and if they mesure out ok I'll just order them. They have got to be done at some point anyway. I will also go to atro and just double check bushing measurements!

I did find a used 9QL4551M back to back im going to get some mesurments and might go that route. the back to back seems like its a way stronger option then what I have now witch is pretty much stamped steel.

Plate type replacement. Used in pairs back-to-back. Sometimes a single one at the rear of an R-model (A DM would use 9QL4551M8's and then an I-beam crossmember at the rear).

I always thought a 351 Cleveland was a lower HP/Torque for cars and smaller trucks made in Cleveland- and Windsors were higher HP/Torque bigger truck engines made in Windsor, Ontario.

I believe the fuel tank is good. when I did run it lower on fuel I did shine a light into it and it looked clean

when I snap the throttle the rpm's don't run up. It immediately drops back down to idle. Truck doesn't have alot of miles, only 160,000. It's just old but other than the occasional surge it runs and pulls great

I'll just chuck these in here NMP

Never too early🤣 Paul

What's your fuel tank look like? You could have gotten some bad fuel or something if there's residue in the tank. We've seen it happen locally around here; an entire fleet was having some fuel issues (all newer trucks), and it turned out to be a batch of bad fuel at the local fuel station all their drivers were going.

Give it a try definitely worth replacing them ! The pump is Ambac worth keeping an ear on too the over run clutch can be an issue! Snap the throttle and listen for it jumping to governed rpm if it travels beyond the governed by more than 50 you may need to have the drive hub serviced!
