Mack 427 Reviews

[chai]

My dad is a 30+ year trucker in the market for a new truck. He's debating the 427 engine but has gotten mixed reviews. You guys are the pros. What do you say? Thanks for any help.

What year and model? Mack made the 427 from around 91/92 till 2007. Startin with the E-7 VMAC-I , VMAC-II, ETECH, CCRS, ASET AI and AC. Now the closest thin is the MP-8 425. All had good points and bad with some worse.
