h67st Posted February 16, 2018 Share Posted February 16, 2018 (edited) This is listed as a B71...I'm not an expert on the model numbers. Very interesting with a 1673 Cat in it. https://www.ebay.com/itm/1955-Other-Makes-Mack-B-71-Mack-B71/232667836785?hash=item362c157171:g:UbIAAOSw-RFacxtD&vxp=mtr Edited February 16, 2018 by h67st 2 Quote Link to comment Share on other sites More sharing options...

Popular Post HeavyGunner Posted February 17, 2018 Popular Post Share Posted February 17, 2018 I thought the b71’s nose stuck out past the fenders a fair amount? 3 Quote The problems we face today exist because the people who work for a living are outnumbered by the people who vote for a living.The government can only "give" someone what they first take from another.

davehummell Posted February 17, 2018 Share Posted February 17, 2018 Boy would i like to have that engine but i would't be able to rebuild it money wise. I used to work on that style engines in 2 autocars for a local coal company Quote Link to comment Share on other sites More sharing options...
Popular Post nasty51ford Posted February 18, 2018 Popular Post Share Posted February 18, 2018 My dad had a 1973B Cat (245 HP with the turbo) in a 66 Ford H100 "Two Story Falcon" he had taken the pump apart, went through it, removed shims, did some other things which I can't recall, but he turned it up, put a 3.70 rear in the truck, and turned 10th gear around in the roadranger, that little Cat would run with 318 green Leakers, and 290 Cummins. It had 1,000,000 miles on it when he sold it, and he had only done the heads the whole time he had it! It still ran great, and had very little blowby, and great oil pressure! Pics taken in "73" You can see the old style "CAT" decal on the back of the cab behind the grab rails in the pic of the left side of the truck 6 Quote Link to comment Share on other sites More sharing options...

Popular Post j hancock Posted February 18, 2018 Popular Post Share Posted February 18, 2018 The brochure indicates that all the B-71s were built with a Cummins NHB 743 CID with 200 HP. The nose isn't the typical extended sheet metal. Looks like a "B-61" front end to me. Who knows what happened. Maybe a B-71 door with tag was installed on this truck 4o years ago? 3 Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...
