cheech147 Posted November 6, 2015 Share Posted November 6, 2015 Looking for some help on the E7 427 Mack Engine. I'm looking at buying a 98 Mack CH613 E7 with a 427 engine. The seller advertises is at 500 hp. I'm familiar with the older Mack engines like the 300's and 350's but the newer ones started to escape me. Guess I'm getting old. What bothers me about this truck is the mileage and hours comparison. It has about 500,000 miles with over 30,000 hours. It is setup with a wet line so I'm guessing it has a lot of idle time on it. I drive a company truck now with only 12,000 hours with 400,000 miles. Can anyone tell me about the engine and what they think of the mileage and hour ratio?
