I have had this boat for 18 years and have gone thru the motor 2 times now, was wondering if any one has ever heard of swapping our a Big Block Ford and put in small block chev. I know the CVX 20 is a heavy boat, but I think a Small Block Chev, with some modifications would put out more RPM's, which would give me a little more speed and possible a little more power out of the hole, Just didn't know if anyone had ever done it and how satisfied they were with the Boats performance?
