No one seems to want to break the ice here so I will. Once they get going, you will get 10 guys suggesting a comp 280H, I will go in a different direction. I'd go with an Isky 280 megacam. Both are close to the same duration, the comp is 230@050, the Isky is 232, but the isky has a lot more lift (.565 at the valve), and more important IMO, its on a 108 LSA instead of 110. Both the Comp and the Isky are .842 "chevy" lobes, you can do better by going to a custom grind form Bullet from their line of .875 lobes, but for an off the shelf cam, I like the Isky. If you go with a custom grind, I would tighten the LSA even more.
Oh, and its gonna need a looser converter. I'd do a converter long before I started worrying about strokers.
