double d Posted April 28, 2014 Share Posted April 28, 2014 A friend that i haul with has a 2000 CH with a e7 350 that is needing some attention. Has 900,000 on it now.It is starting to leak a little from the back head gasket. He bought it with 600k on it and got some records with it but nothing on engine internals. it was a Lee Transport fuel hauler from New Jersey and they have a good rep on keeping up with their maintenance. He is leaning towards 2 reman heads and a cam and injectors and leaving the bottom end alone as it uses no oil, good oil pressure etc. He is looking for advice on what to do. He wants a little more HP but not anything that will chance damaging it over the long run. We run all flat ground pulling a feed trailer for poultry farms. Any advice would be greatly appreciated.

gearhead204 Posted April 28, 2014 Share Posted April 28, 2014 if my name was on the door at 900,000 miles it would get a full in frame, your way to close to every thing to come back at a different time and redo 80% of the work to do pistons liners and main and rods. labor and down time cost more than parts! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/35548-e7-350-rebuild/#findComment-243582 Share on other sites More sharing options...
Dirtymilkman Posted April 28, 2014 Share Posted April 28, 2014 Gearhead is right. Besides the leak could be liner protrusion.... Quote Link to comment https://www.bigmacktrucks.com/topic/35548-e7-350-rebuild/#findComment-243597 Share on other sites More sharing options...
j hancock Posted April 28, 2014 Share Posted April 28, 2014 I will third that motion.At 900,000, you should do it all. If you want a little more hp, you really need to look at the bottom end.

double d Posted April 28, 2014 Author Share Posted April 28, 2014 Thanks for the replies. I should have been more clear in my post-he thinks the bottom was done at 600 from talking to the mech where it came from. But need to get it apart to see how things looks. What would he do for more hp in the bottom end and what injectors up top?

double d Posted April 28, 2014 Author Share Posted April 28, 2014 He's leaning towards your advice to do the bottom while he's there. What do we do to get some more reliable horsepower if we're going to do everything? Any and all advice will be welcome on what to do how to do it.

Dirtymilkman Posted April 29, 2014 Share Posted April 29, 2014 Google RFI that's Rochester fuel. They have great injectors. I run stage 2's in all my trucks. Better mileage and more power when u poke the dog in the ass. They can also help u with pump and turbos Quote Link to comment https://www.bigmacktrucks.com/topic/35548-e7-350-rebuild/#findComment-243713 Share on other sites More sharing options...
j hancock Posted April 29, 2014 Share Posted April 29, 2014 The bottom end can take a HP increase provided it is checked out to confirm specs.I mistakenly thought you had 900,000 miles and wanted to boost HP. With 300,000 miles, pulling the rod and main bearings will tell you where to go next and it would be good to do with more HP and also check the oil pump.

masterwelder Posted April 30, 2014 Share Posted April 30, 2014 Wouldn't hurt to call Antrim Diesel in PA either. Just had em on the phone talkin turbos. They know how to do it right.
