The local dealer in lloydminister says they can look up VINs of any truck that they didn't sell, lol. but mack customer care guy says this vin had an e5-240, and the seller claimed 240... Doesn't compare to the western star at work with a 650hp Cat, that's for sure. I wasn't able to find any markings on this engine at all. Where are they supposed to be? Also, any idea what kind of engine would be most "swappable" when this one craters?

The trailer is heavy..for a goose neck... But the guy that i bought it from was pulling it with a 3/4 ton Chevy! Also, 4 gears split +low + reverse =10 speed right? It has a road ranger sticker on the dash, but part of it is missing, so i don't know what make. Would i be better off going up a long incline holding 80km/h in 8th @1400rpm, or 75km/h in 7th @1900rpm? What would be the easiest/ most reliable way to add a few ponies? Or do i just need to replace the turbo and look at refreshing the engine in the near future?

25 years is considered a classic right? I bought my first truck this year, and i have a couple of questions. First, does anybody know the difference between a CM400 and CM422? My registration papers say Mack 400, but the Mack customer care guy says its a 422 VIN. He also says that the engine is an e5-240. Is this engine supposed to be gutless?? It seems like 240 horse should be performing better than this... I'm having a hard time holding highway speed with an empty goose neck trailer. It is probably an over kill set up; steel deck with 10T picker, 20T winch, and a 100% steel tilt/roller deck goose neck. My axle weights are 5200/6800/4200kg empty, so its about 35,600 lbs. It feels like I'm sailing with the anchor down, or am i just expecting too much from a French engine? Can anybody tell me the approximate torque rating of an e5-240?
