mack mhe9 Posted September 19, 2013 Share Posted September 19, 2013 I'm sure I know the answer already but I was reading my 1989 superliner brochure And in the spec area.They say the E7 was up to 425 Hp??I know it's just wording but what the hell, where's the 425hp engine.

Superdog Posted September 19, 2013 Share Posted September 19, 2013 Far as I know,they didn't get it bumped up that high until '95 when the 427 and 454 became available.

mack mhe9 Posted September 19, 2013 Author Share Posted September 19, 2013 Like I said I knew the answer just thought it was mean that they would say 425 and not make one.

bbigrig Posted September 24, 2013 Share Posted September 24, 2013 In 1989 when Mack unveiled the E7 engine they also announced that a 425hp version would be available in 1990. It never happened, and the 427 was not put into production until V-Mac II was introduced in 1995. The Superdog was built till late 1992 so it makes sense why it would be in the brochure.
