Top Speed problem in 1989 Econoline 350 RV

06-22-2008, 11:14 PM
I own a 1989 Econoline 350 Coachman Catalina RV with a 460 F.I.

It starts and runs great. Accelerates fine, etc. Problem is that it's top speed is 55 MPH. I cannot go above 55. No evident problems. It does not sputter or run rough. 55 is just as fast as it will floored. Any ideas. Adam
