NC IL I80@68 | Got a '97 CH with E7-427 , 18sp and I think 3.85 or somewhere around there , all Mack . Just passed 800,000 and 31,000+ hrs . Know where it came from new it's had pretty good care down through the years . I did the pump and injectors couple yrs ago , engine has had nothing else done . Couple clutches , air compressor , radiator and charge air coller etc . Uses gal oil/10,000mi . VMACII I think . Is little slow on low end but has done pretty good gor me and my son, previous owner . He bought it at around 500,000 . He bought a 2000 Pete 378 500+ N14 18sp and all that then I got the CH . The 427 has nowhere near the low end torque the N14 has but can't expect it to . Later on he took a load of corn with the Mack when he got back I said what do you think , reply was except for taking the hill 10mph slower the Mack was a better ride . He probaply won't fess up to it now . Anyway I have driven them both , if you go for class etc the NAT approved and all that the 378 is a cool truck , dual air cleaners , stacks , lights and all that . But the Mack is way better riding , easier to get into and out of , seeing ahead , no air cleaner or exhaust to look around of , Mack has duals too but more behind cab . By the way the Mack spent most of its miles doing dump trailer, belt trailer and lowboy work . Still runs 30,000mi/yr construction/dump/farm work . Several have told me that this vintage was one of the best Mack engines built and is not uncommon to go 1mil mi before major work , don't know but will find out one of these days . Somewhere late 90's early 20's when they went to the unit pump , the style after this one, they had some camshaft problems , a lot of them were done on warranty probably some were not .I really can't say for sure , then the egr thing and some other issues , seems like you hear good and bad on the later models . I would like to find another one some day set up like mine but they are hard to find in good condition . | |
