KB1785 Posted January 31, 2021 Share Posted January 31, 2021 I have been interested for a while in a B model build. I have a truck that I have been looking at that is decent and intact and was running when it was parked several years ago. Some rust but not too bad. I plan to use this to pull trailer and haul some smaller equipment, etc. and be set up with a 5th wheel and pintle hitch. My question is for someone that may know more about this particular model and may have gotten into this in the past is how difficult is it to change the old engine out which is the old non-turbo diesel to a more modern 300/350 hp mechanical type engine. Just curious about wiring, clearances, engine mounting in the frame, guage connections and functionality, radiator cooling capacity and the like. In addition was looking at changing the old quad box to a 7 or 8 speed and curious about any mounting issues, reman bracketing necessary. Has anyone replaced the front axle with something a bit more modern and if so recommendations. Evaluating options at this point in time and addressing the costs of these options. Thank you for your time and input and patience with my questions. Have lurked on here for a while but my 1st post. I have an old RB model dump truck and have loved Macks my whole life but just something special about the B's and would love to take the project on if it makes sense and not too crazy. 1 Quote Link to comment Share on other sites More sharing options...
