steve s. Posted March 7, 2010 Share Posted March 7, 2010 Yes, the frame will handle a diesel engine. The obvious choice would be a Mack, and if you had another B model donor truck, the job would be fairly easy. Otherwise you are limited only buy the tape measure, your skills, and your wallet. A lot would depend on what you plan to do with the truck, and what you want it to do for you. Will it be a play toy, or work for a living ? Do you want big power, or economy ?

JerryB Posted March 7, 2010 Share Posted March 7, 2010 do you think i can put an old cummins in it?Cummins is too long. I noticed an ad wanting an offer for a 673P here at BigMack and the 673P is bullet proof and will tweak up real good. http://www.bigmacktrucks.com/index.php?showtopic=12447 Quote Link to comment https://www.bigmacktrucks.com/topic/12907-can-i-put-a-diesel-in-a-b-42/#findComment-50777 Share on other sites More sharing options...

I am looking at a 1961 B42. Will a 471 DD fit?

DMorgan Posted March 10, 2010 Share Posted March 10, 2010 I am in the same boat. I am looking at a 1961 B42. Will a 471 DD fit? Thanks Dieselman, I have a 421 that we would have liked to put a diesel into, but we have not found an engine with more than 250 HP that will fit into it. Another thing you have to think about is how much cooling capacaty the engine needs. I do have some info that says that a 471 Detroit has 160 HP @ 2100 RPM., is 42 inches long, 29 inches wide, 42inches tall, and weighs 1780 LBS.There is a website you can go to that will tell you dimensions for Detroit, Cummins and Cat engines. It is: http://www.adieselengine.com/new page 1.htm. Hope this helps, Daniel Quote Link to comment https://www.bigmacktrucks.com/topic/12907-can-i-put-a-diesel-in-a-b-42/#findComment-50952 Share on other sites More sharing options...
ThaddeusW Posted March 10, 2010 Share Posted March 10, 2010 I am in the same boat. I am looking at a 1961 B42. Will a 471 DD fit? Thanksthe 4-71 is pretty short so it should fit. The naturally aspirated 4-71 should yeild about 159HP which is half the power of a 318HP 8v71. With a turbo you could get about 200-220HP and around 450-495ft/lbs from that little 4-71. Don't think it will stack up to a turbo 673 in terms of power but it will have more power than a gasser. Quote -Thad What America needs is less bull and more Bulldog!

mackmixer Posted March 10, 2010 Share Posted March 10, 2010 My old B-42 was repowered with a Cummins diesel, a CF-160, sometime in it's life. Also fitted with a 20 speed quadraplex rather than the original 10 speed. This is a 160 hp engine rated at 2600 rpm.I suspect parts for the old Cummins are hard to find. Have not needed anything.....yet. Quote David Link to comment https://www.bigmacktrucks.com/topic/12907-can-i-put-a-diesel-in-a-b-42/#findComment-50986 Share on other sites More sharing options...
