Thank You very much VMAC3! I have been searching for this exact information for a week and nowhere on the web can I find any literature or history on the E7 engine. I have just purchased a 1997 CH613 Gold Dog Mack with the E7-400, T2130 13-SPD, and 3.78 Mack rears. The truck has 425,000 original miles. I believe that the engine is a VMAC2 but I have not ran the VIN or engine serial number to verify that yet. It is by far one of the nicest 23 year old trucks I have ever seen. I should preface this with we have owned a 1996 CH613 with the Full Mechanical E7 for over 20 years now. It has been turned up quite a bit and it will run circles around our 450HP Cat 3406E's. This 1997 Mack that I just bought will be our first Mack with any electronics on it. I was somewhat familiar with the VMAC3 engines but was totally unaware that Mack actually produced an E7 with a electronically controlled In-Line Bosch Pump until recently.

Can someone please give me somewhat of a detailed history of the E7? I'm more concerned with the how the fuel system has changed over the years it was produced. (From full mechanical to full electronic controlled)

Can anybody give me somewhat of a detailed history of the E7 engine? I'm more concerned about how the fuel system on the engine changed over time. I'm aware that a full mechanical engine was made and that a ECM controlled engine was made. However I've recently found another model for sale that uses the mechanical fuel injection pump but utilizes what looks like a electronic stepping motor to run the throttle. We have a full mechanical E7 in our fleet and we're convinced that it is the best engine to ever roll off of Macks assembly line. I would just like some history on how the E7 changed over time and what models proved to be the most powerful and service free over time.

How many total miles were on the truck/engine when you had the camshaft replaced?

Not that I am aware of, the seller said that it did not have any egr garbage. I have not personally seen the truck, it is located about 600 miles away from me. The truck has 245,000 original miles.

The truck has 245,000 original miles. It has been in the oil field industry in the south. Mack 18-speed with Mack Axles. Super clean and straight truck from what I can tell

I am looking to buy a 2003 CH613. The seller claims that the truck has a 460 E-tech engine in it. I know virtually nothing about the electronic Mack engines and was wondering what issues (if any) you guys have had from these engines? Also how do these engines perform compared to the mechanical E7? We currently have a fleet of five trucks, only one of which is a Mack with a mechanical E7 in it and it will run circles around our 450hp Cats.
