saw this in the comp site. specs said good bracket/ high performance. How would this cam work in my 9.5 355 with auto and 3.73 gear. Comp xtreme marine 290h

Derek,
If you look at the entire catalog, you will find that plenty of the marine cams are also listed in the "car" section. Same cam. The cam doesnt know if its in a boat or a car.

"Some" of the marine cams have extra duration added to the exhaust side to help with those boats that run with water manifolds. I ran one of those in a car application and it was fine, but may or may not have been ideal.
