Kansas farmer Posted April 3, 2014 Share Posted April 3, 2014 Just wondering if you guys knew what kind of horse a guy could get out of an e6 and still be practical to drive. Hopefully within about a year I am going to inherit a bone yard of trucks so to speak. There is a good superliner that I think would be worth fixin is I use parts from some of the other trucks. But really wondering about horsepower. Any thoughts would be helpful I would like to try and get my ducks in a row now.

terry Posted April 3, 2014 Share Posted April 3, 2014 I do believe there were factory E6 350's, but i'm sure somebody will know more. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/35288-e6-350/#findComment-240537 Share on other sites More sharing options...
Kansas farmer Posted April 3, 2014 Author Share Posted April 3, 2014 Sorry I left out the 350 on my post. They did make a 350 we have two of them. One is turned up to about 375 on the pump but just wondering with some injectors and a turbo what a guy could get out of one and still be practical to drive.

Bullheaded Posted April 4, 2014 Share Posted April 4, 2014 485, then they break in half if you are not paying attention pulling any kind of hill. At least that was my experience when I ran them. At that setting the engine and exhaust temps would skyrocket very quick if you got into a big hill pulling heavy and you'd have to back off it.That was on an 88 E-6 350 4 valve by the way. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/35288-e6-350/#findComment-240631 Share on other sites More sharing options...
b61mack Posted April 4, 2014 Share Posted April 4, 2014 350 HP is just about the limit on the E6 and make it live, you only got 672 cubic inches. I know a guy that had 900,000 miles on a 84 Ultra Liner that just changed the mains and rods at 300,000 miles each time. if you want more power I would go with an E7 at 728 cubes.

Dirtymilkman Posted April 4, 2014 Share Posted April 4, 2014 I was told that the E6 bottom end isn't strong enough for over 400 horse. We always ran ours for 900,000 plus miles before mains or anything. The last ones were a great engine. But it all depends on who's pushing the pedal.

Bullheaded Posted April 5, 2014 Share Posted April 5, 2014 I've seen two split the crank and block in half with the power I mentioned. But they were company drivers. They will make that power....you just can't use it all, all the time.Don't need to go that extreme anyway. My old E-6 350 would do anything a STOCK 475 Cat/ 500 Detroit would do with just a good pump tune. But it was geared pretty low though too.

Dirtymilkman Posted April 5, 2014 Share Posted April 5, 2014 I have a 1990 ch that is totally stock. Less than 600,000 miles. We put a new injector pump on and left it at stock setting. It put 336 HP to the ground. Quote Link to comment https://www.bigmacktrucks.com/topic/35288-e6-350/#findComment-240679 Share on other sites More sharing options...
b61mack Posted April 5, 2014 Share Posted April 5, 2014 At factory setting they had as much power as the 400 Cummins. at work we have a 90 CH with a E6, 9 speed, we haul a # 50,000 excavator no problem.

Bullheaded Posted April 5, 2014 Share Posted April 5, 2014 Yep my old 88 R Model (when stock) went up the 8% grades here at 140,000 pounds in the same gear as my new 505 DD15 Detroit, although at a bit lower road speed.I love the E-6.

mack mhe9 Posted April 5, 2014 Share Posted April 5, 2014 There was someone on here a couple weeks age making over 700 with a e6. It was a pull truck. Quote Link to comment https://www.bigmacktrucks.com/topic/35288-e6-350/#findComment-240741 Share on other sites More sharing options...
keg1 Posted April 6, 2014 Share Posted April 6, 2014 I ran with a company Peterbilt today when we came to the first big hill I figured he would be pushing me up it but I pulled away from him by quite a bit. What a feeling. Quote Link to comment https://www.bigmacktrucks.com/topic/35288-e6-350/#findComment-240790 Share on other sites More sharing options...
