{"text":"Have any of you guys ran both motors? How do they compare? I run a 445hp MP8 in a 2015 Pinnacle with a 13spd. Compared to a C12, C13, 12.7, MX-13, etc it's a very hard pulling motor. I've never had a chance to run a Mack 427, 454, or 460 vs one. I did talk to a guy in my company that used to run a Vision with a 460/13spd, and he loved that truck! He was pretty ticked off when they finally retired it with well over one million on the ticker. I guess she was running great, pulling hard, and using nary a drop of oil to the very day they got rid of her. That was several months ago and the old guy is still pretty steamed about that...\n\nI have had the chance to run a 2007 Vision with an AC380/410 and a 10spd auto w/ clutch several times lately. The truck rides great but is totally gutless compared to an MP8. I know the older Mack engines liked their higher revs, but you can't keep it up high with a 10spd. When I'm pulling 75k with that truck it's laughable trying to get up to 65mph. Climbing out of the big hole in 9th and 10th is about like watching the grass grow lol.\n\nWhat's everybody's fav Mack engine pre-Volvo and why?","pics":"[]","canComment":true}
