Well I dunno much about much. Some quick searching on this site found some ratio charts 12 speed Mack is the multi speed built by Mack for Mack Thermodyne motors So it is the true multi speed standard torque curve motor for Mack trucks Your 9 speed isnt that much different so I'm not sure your gunna achieve a lot by swapping transmissions to a RoadRanger Thinking driving style might achive a lot more, dont let it lug as much and drive it in the rev range that it is designed to be driven in maybe Bare in mind I have no idea what your motor is The weight your shifting has little effect on the way it should be shifted, the transmission should always be shifted thru gears at the desgined rev's As you can see the ratios are pretty similar Paul

Good morning and welcome

Gotta be a proud and emotional time, or at least it would be for me Great stuff and thanks for taking us along for the ride Paul

Pepper in it, leave the cap off and when hot crack a few eggs in That should seal it up tickety boo LOL In all seriousness I reckon the cost of a re-core pales into insignificance compared to cooking a motor 5 grand in Australia to re-core a R model Mind you Australian R models are all specced with the biggest radiator available at the time Apparently the US and no doubt Canada had many options and it may well be a lot less Paul

Looking very impressive, good luck for Sunday and hoping it all goes smoothly Paul

Here you all go, the video flogged from Facelessbook Hopefully the link works, let me know if it doesn't And the photos that were with the video I believe Jason Jake Coblentz pictures and video Paul

Good luck for Sunday, she's really starting to come together now Paul

This is worth another look, made me chuckle Paul

I was watching a video of this truck on Faceless book a few minutes ago, looks sharp and sounds good Paul

Dunno, just make a system up I guess Welcome Paul

I use PVC coated stainless steel cable ties, they last forever and look neat as a pin Looks really good Paul

Rolls Royce diesels were available in Australia into the 80's A new White Road Boss could be purchased from White with one Paul

Yes he is very much alive and kicking Paul

We can try Joey, I have no idea about this type of compressor However it is all loosely based on the same idea So I guess I would be trying to see if the wire to engage the compressor has power and start there If it's freezing up thats a whole different kettle of fish Paul

Is the compressor engaging? Paul

Just saw these, might be of interest Paul https://m.facebook.com/story.php?story_fbid=395940595755453&id=103304275019088&sfnsn=mo

Welcome the duck Paul

This may help Paul

I hope they are okay, I have spent the money a little while ago Have to chop mine up as it is for LHD and I have to make mine RHD There was a thread on here some years ago and these are the best for under the dash type of AC in a R model Paul

Looks pretty darn good to me, well done, share more photos, we all love photos Paul

Well winter is only weeks away so small appendage has a excuse 😏 Paul

So maybe something like this will help https://www.ubuy.tn/en/product/1PW7N0ZFC-jy-performance-4-inch-diesel-truck-exhaust-muffler-7-x-24-body-30-whole-length-straight-through-stainless-steel-welded-on-resonator Paul

Oh dear, you blokes wont approve of the 6 inch stack for my Mack then 🥴🥴 Paul

Party time young fella, I might be a little late, dunno with time zones But better late than never Hope you had a great day Paul

I reckon theres some good thoughts here There places that custom make rings for old motors of any description so this shouldn't be to big a drama to have a go at Paul
