I am mystified as You about various cams. My Mentor and Mechanic can tell a modified cam. I cannot. I am told that one of the reasons a Rover V8 in a Morgan responds very well to cam modifications. Seems the Rover cam is designed for a heavy SUV. If the Modified Cam is designed for a Morgan +8 it will be much more responsive and suitable for a Light Sports Car. There are other factors but frankly I am too inexperienced to identify them. When I changed from a Carb to an aftermarket EFI that was not designed for emission Laws My +8 Bitsa came alive. Not sure I have any more horsepower but the character of the engine now matches the needs of a Light Sports Car better than it did. I am now tempted to install a modified cam and try for more improvement.
