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
