30a rider.....that second cam sounds better to me....that's quite a change in duration (for the better) and I like the 110 LSA much better. Will definitely be torquier than your first choice. Nothing personal against Comp Cams, but I would get a couple other recommendations. Try a smaller place like Isky, or Howards Cams...they've been around forever, and they're all racers and engine builders. It's nice to get opinions from the source, and not from someone looking at a computer screen, just my opinion. My last few cams have been from Howard's Cams, and I couldnt be happier, but there are lots of others out there.
