Bass21x Posted March 20, 2019 Share Posted March 20, 2019 Got a em7 275hp all mechanical injection pump out of my Rd690s! It spun a rod bearing! I got another em7 300 hp engine from my buddy out of a ch model with an electronic injection pump on it! My question is should I put my mechanical pump on new motor or try to convert my truck to the electrical pump?? Time is of the essence!

Lmackattack Posted March 20, 2019 Share Posted March 20, 2019 i dont know what all is involved to convert back to mechanical vs Electric but i never did like the throttle response of the electronic macks of that era. they felt lazy and slow 1 Quote Link to comment https://www.bigmacktrucks.com/topic/56263-em7-swap/#findComment-418644 Share on other sites More sharing options...
