Jocko Posted November 3, 2016 Share Posted November 3, 2016 Hey guys I might be buying an old rd tractor with a 237 could I slap a 350 Mack motor in it would it bolt up thanks Quote Link to comment https://www.bigmacktrucks.com/topic/47554-350-in-an-old-school-rd-mack-with-steel-hood-can-it-fit/ Share on other sites More sharing options...
j hancock Posted November 3, 2016 Share Posted November 3, 2016 Pretty much but don't forget the charge air cooler. Part of getting the 350 HP will be cooling the compressed air. An old RD with a 237 didn't have a provision for the cooler. Quote JimIt doesn't cost anything to pay attention.

tjc transport Posted November 3, 2016 Share Posted November 3, 2016 i am sure it can be done, John Lacey trucking here in New Jersey has 73? i think it is DM800 with a newer 350 electronic engine and 8LL trans swapped in it. truck used to have a V8 in it. when the V8 went he put in the electronic 350 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..
