JoeH Posted December 20, 2023 Share Posted December 20, 2023 Mechanical is always your friend, manual or auto. Would be a major headache trying to graft a computer system into another truck. Apart from that I got nothing. Using what's readily available means parts to fix will also be readily available.

BOBWhite Posted December 20, 2023 Share Posted December 20, 2023 I'd agree with the DT466 idea since cummins can be a bit pricy to find. Plus DT466 is rebuildable!! John Deere engines can also be pretty easy to find and are about the same as a DT466. Eaton 6 or 7 speed is what I would go for but if you feel up to plumbing in air lines or even driving with twin sticks you can put any transmission in you want.

r8f1k Posted December 20, 2023 Author Share Posted December 20, 2023 I'm game for just about any combo that is EASY to find parts and EASY to maintain. Nothing worse than finding a project and all the parts to support it are like hens teeth. In the last 25 years, I have done DOZENS of restorations. Cars, tractors, soda machines, jukeboxes, pinball machines, vintage machining tools, antique farm implements, furniture, clocks, and on and on.......I'm a glutton for punishment. I was thinking it might be easier to buy a whole truck to swap parts off of, like a pre 1994 International with engine/transmission and axle. Swap it all over to a Mack B61. I would like a stick, but my wife may also want/need to drive it. I kinda want to put a roll back on it to haul equipment rather than use a trailer, might also help with the ride. Anyone know what is the limit for posts on this forum? I got a notification that I had met the maximum amount of posts for the day. Is that for new guys?

There was a fellow a few years back that bought a bus and used the whole driveline for his B. Front/rear axles (hydro boost), motor/trans. He did have to narrow the front axle to fit . B's are pretty narrow. All mechanical, no computer if you can find an old enough bus. I'll try to find his build, there were tons of pictures. Quote Larry 1959 B61 Liv'n Large......................

r8f1k Posted December 22, 2023 Author Share Posted December 22, 2023 I have found a decent B61 with a Mack diesel in it. Owner says it is a 673. Any thoughts on keeping the 673 and swapping a better/more roadworthy transmission? It has a tandem axle, I would be willing to swap an axle, but what is the IDEAL thing to look for? Factory air ride? Thoughts?

JoeH Posted December 22, 2023 Share Posted December 22, 2023 Ideal is go to a junk yard and see if they have a rear single axle cutoff with a suspension you like and axle ratio that'll get you the top speeds you're looking for. Take note of outside frame rail measurements, I believe Mack frame rails are a slightly different spacing than other manufacturers. May require shims of some sort to match up another brand suspension to the Mack. My Mack experience doesn't begin until you land in a mid 1970's R model. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73665-mack-b-model-customrepowerchassis-swap/page/2/#findComment-543916 Share on other sites More sharing options...
JoeH Posted December 22, 2023 Share Posted December 22, 2023 Note that trucks of this era were built when highway speed limits nationally were 55 mph, so that's typically what you can expect any old dog to be built to do. Gearing an old dog to go 75 mph is probably doable, but remember the steering geometry and linkage may or may not be happy going that fast. My '79 R686ST keeps you on your toes to make sure you stay in your lane, albeit it's a top heavy truck with light frame and springs.
