Cam Questions

The B303 cam is a horrible choice in this application. It has a very poor LSA. A higher LSA is key to getting the car out of the hole with an AOD. The B cam is also a very poor choice for forced induction because of it's LSA.

Since you have chosen iron heads that will more than likely have valvetrain setup for a maximum lift of .500, I would recommend a Steeda #18 cam.

.480/.480 220*/226* LSA 115.

You could also choose an E303 .498/.498 220*/220* LSA 112, but I think the extra duration of the Steeda cam will work better for you with the supercharger, and the very good LSA will allow you to make power down low. The P heads should be very good at making low end power, while the track heat intake is more setup for high rpms.

If you choose to go with a Xtreme energy series cam you might as well step up to some different heads because the cost of adding high lift springs and components will make the GT-40P's much more expensive. People seem to forget the XE series cams(which I think are junk) are very high in lift, and very short in duration. Their advertising says "more power than other cams with the same duration" or something to that effect. Wow. Pretty impressive considering their duration compares to extremely mild cams.

The Cobra cam is very weak. It's a really poor choice for any performance application if you don't use 1.7:1 rockers, and even then, it's not good. The one advantage the Cobra cam has in this case, it's a good stock AOD cam, LOL. Since you're not stock, and you don't intend to be stock in the future, it's a poor choice.
