Been looking at a lot of boats, always stayed clear of the boats with Fords, because im a chevy guy. But in reality I have seen a lot of nice boats with 460 power plants. I want to know if there is really a big longevity difference between the 460 454 and 455, which I see in the boats most often, especially the 455 olds. I know it has its issues, what should I be concerned about with the 460? Im pretty familiar with the 454. This is stemming from a couple boats I like that have the 460 and Berkeley jet versus the 455 boats I have seen with jacuzzi and Berkeley, pretty mixed. Oh, im looking at mini day-cruisers in the 21-22 ft range. thanks!
