Has anyone ever dynoed a dual wheel F350 or alike? Ive just dynoed mine and have found that the dual wheels and tall gearing has really affected the power readout? its a brand new 460 with cobra cam, forgies, bal and blueprint, extractors, and a holley 850 double pumper, ect ect. i have read that these engines in stock form have around 400-450hp at the fly, so im assuming that with the mods it would be more like 500hp? Anyway the result was not much better than my old 460 engine that was stock and a little tired. my new engine pulls twice as hard as the old, so y does this not show on the dyno?
