Just posted this in another thread. I have '85 v20. Just ran it for the first time with 2008 etec 200HO yesterday. Didn't have it propped quite right as it was only turning 5100rpm, but at just above 50mph running on glass it started to chine walk. We had a very light load (half tank fuel, no gear, 2 adults). Prop was 21" Viper. Gonna try 19" prop.
