I haven't seen much difference other than marine cams aren't necessarily ground for way high rpm performance. You want to make good torque at the bottom so you don't have to wing the motor coming away from the dock to get the boat moving. Most Comp automotive cams are ground on a 110 degree lobe separation angle. This cam of yours is ground on a 112 degree LSA which should show real good intake manifold vacuum for power brakes, etc. Here's the timing card on your cam. Note that in the installation notes, it calls for better springs. The springs to use are shown on the card....
