More power from my 360 Duster?

I appreciate all the advice! I think I will do alot of these recommended upgrades before next race season. For now, I think I will try a cam swap and maybe some drag radials just to keep my wallet from imploding from everything I want to do and then see how it does at the next run.

-In response to Rumblefish360 about the 4.10 gears. I would like to get lower gears if that would help my car alot. The only drawback is it wouldn't be very highway friendly driving to and from the track.

-I am currently running BFG Radial T/A,s front and back with 245/60/14" mounted on the back and 235's on the front. I also have the superstock springs in the rear with the mopar adjustable pinion snubber 1" from the floor. If I keep my current gears, what size 15" drag radial would work best, or would it be better to maybe go with 4.10's as mentioned with a taller drag radial? Or should I just swap gears before going to the track. I just finished setting the 3.55's, I think I would buy another third member this winter if I do a gear change, as doing it right building another third member with new gears may cost a little.

I read and checked out the voodoo cams from Lunati as mentioned. Does this one look like a decent grind for my current setup ?

How would I determine the proper valve springs for the cam I choose? Would I need to measure for new pushrods if I change the cam and lifters?
Thanks!!
