Just to add a little bit more to this discussion, I think the reason why cams in the 220's run so well in our trucks is because they make high torque averages across the rpm range. Larger duration cams would probably go faster if the trucks running them had real short gear sets to take advantage of the higher narrower power band. Unfortunatley the truck intake manifolds won't allow the engines to maintain that high rpm power so it would require at least a car style intake to do it.

If you guys noticed, the "guinea pig" has a ls6 intake on there, so unfortunately it won't be a comparison with the truck intake, but it does show potential of the cams with the mods to support the added af. I can't wait to see the results, I might just wait to order my cam till I see the result.

With the extra intake duration and low lsa that cam should pull good to 6Kish and make damn good power getting there, it oculd be better with a couple degrees advance but it should do well for you IMO.
