CharlieK Posted July 12, 2015 Share Posted July 12, 2015 Hey Folks!I've been putting off asking this for far too long now, cause, well.... I kinda feel like an idiot asking :-)I have a 2000 Mack CH613, 350, with an Eaton Fuller 10 speed. I've been wishing for a lil more "umpf" on some of our south eastern Minnesota rolling hills. I'm considering getting rid of the 10 speed for a 13, but I don't think I want to stop there.So....1) I've been told by a gent that has run Macks for a long time, that I have an "E-Tech"... Except I can't find the word E-Tech anywhere on the truck. I only find an "Engine Model" tag on the valve cover, that says "E7-350". How do I know that I have a E-Tech? What is the difference between an E-Tech and a non E-Tech?2) Whether I have an E-Tech or not... What kind of power is this thing capable of? Displacement is listed as 728 cu in, which, unless I'm seriously mistaken, is the same as the 460. Is the only difference between the 350 and 460... injectors, turbo, possibly a cam, (and I think I read, possibly a bigger radiator)? Can I turn this into a 460?3) I do not currently have a jake brake. What is involved in putting one in? Thanks!

Timmyb Posted July 13, 2015 Share Posted July 13, 2015 I think in your situation pictures of your engine would help guys on here diagnose which engine you have. As far as hp increase, im sure you could. Try a mack dealer or read some older threads on here and get some ideas. Tec brake does engine brakes for macks.

turckster Posted July 13, 2015 Share Posted July 13, 2015 Being a 2000 model its an E-Tech engine unless someone did some creative swapping. An E-Tech has 6 individual electronic injection pumps mounted to the block where as a regular E7 engine has an inline injection pump mounted to the right side. On the valve cover info tag both engines are referred to as E7 engines. Horsepower wise, the engine is capable of 460 hp. From a 350 to a 460 could require new turbo, injectors and engine ecu programming. It could possibly require more, not real sure. If the camshaft is powerleash compatible, a simple rocker shaft assly change, valve covers and some programmming.
