Will a 6-71 or a 6-110 fit in a B? 6-110 is only 660 cu.in which is.   less than a 673. Side supercharger may be an issue.

I hoping that all these post help someone out trying to do it.  

Thanks!  How did they do the exhaust manifold on the drivers side.  My stock one will run right into the steering box.

So here it is.  I know a lot of people aren't too happy to see a "Slime green Dripoit" in a B, but I have my reasons.  None of them are hauling 20 ton up Mt Everest or winning the Indy 500.  Just love the sound of a Detroit and the look of a B-Model.  Had to get pretty creative with the drivers side engine mount.  The steering box was in the way. So i built a engine mount that brings the Detroit mount forward 4".  Then I had to make a frame mount that could "Sqeeze" back under the steering box as far back as possible.  My first attempt I tried using the stock Mack frame mounts.  Even using my homemade engine mounts (reversed side to side from the picture) they would not bring the engine forward enough to clear the firewall or allow an exhaust manifold to be installed in any direction. This was the best solution I could figure out. Exhaust manifold will still be tricky.  I have built the other side frame mount and I am able to use the stock Detroit Engine mount(Sorry no pic it was late last night when I got it built and the paint was drying".   Now to the cradle front mount... 

Thank you all for your input.  I'm leaning Black.

I am thinking about frame colors.  I have purchased the body paint and will be going "Classic" Candy Apple Red Cab, Hood and Grill Shell.  The Fenders and Headlight surrounds will be Black.  I was originally thinking Black frame, but I guess that frames came Factory red for certain years.   

Bondi is about $20 a gallon at Wal-Mart and $30 at Advanced Auto parts.  I have found it for $15 on sale a couple of times.  

This weekend project.  The fenders are going to be black so I'm trying to get them straight and use not 5 gallons of bondo.  

Its hard when you have a day job and family, not too much time for "projects"  

The 4-54 has a bad turbo and ran away.  There is just a touch of oil on the stick. I bared the engine over by hand and it feels ok.  My original plan was the 4-53 but once I found out it ran away I wondering if I'd be better off with the 6v53.  I think Harbison has a 6v53 in one of his B's.  

Please don't shoot me but I may have found a solution to the junk 401.  I just bought a 6v53 and a 4-53 (package deal).  The old mack has a TRD77 10 speed.  I would like to mate this to the 6v53.  I think the TRD77 has SAE 3 bell.  Can I bolt the two together?

all depends what you wanna do with it. 401 is great to drive around empty or haulin a load of potato chips. otherwise they were underpowered and overworked. motor swap or chassis swap. few things come to mind if you just want a driver is an 80s or 90s ford F600 or bigger, usually had a 8.2 diesel or a 3208 cat or a B cummins if your lucky

Could I run an 8.2 against the little duplex?  I have a silly idea...What if I put a 300 6 in it.  125hp and 250ft/lbs, about the same as the 401.  

Just found a DT466 and 6 speed manual about 3 miles from my house.  It runs and drives.  Might be the donor.

JHancock,

Thanks again for more great info!

DKWIDK

Did you ever get any info on DT466 retrofit?  I just picked up a B42 with a junk EN401.  Would like to keep the duplex tranny and just bolt a DT466 in her. 

 

What do you guys think about DT466?  They seam to be plentiful and relatively cheap. I would like to keep my original 5 and 2 speed.  Will I need to use the bell housing from the DT or will the EN401 bell?

Oh absolutely you need to do what you want to do that was just a suggestion easiest way to cure the problem plenty of parts around just a matter of changing a couple of motormounts driveline shopIf I were you I would start asking around especially on here p.m. Chevy 41 is usually the best source.... good luck... bob

Thanks I will PM once I get her home.  If all goes well she will be in my garage tonight.

429 Ford and a c6 not that hard to replace with updated drive train good luck... bob

Kind of had that thought, but I think I want diesel.  My father had a 1974 International Fleetstar with a 6-71 Detroit.  The best sounding engine IMO.  I know they arent power houses and they leak oil,  but they are tough and would be cool.

401 junker. . not worth wasting time with

 

What would be your suggestion for replacement engine?

Anybody got a connecting rod for this old girl?

Here's a bigger picture of the engine,  Maybe someone can tell me if its a 401 for sure.

That be a connecting rod sticking through the side.  Can you still get parts for this engine?  I think it 401ci.

I believe they dragged it to its resting place with a tractor... So maybe it will roll.  By the size of the tree I say she's been sitting for 20 years or so.

Hopefully that won't cause me too much grief getting her out of her tomb.
