Hello,

Your cam is smaller than the head capacity by a ways. You definitely need more cam!

Other things seem out of place

"6500 & 7k the 260 cam pulls it a little too slow , only need 7k MAX rpm"

if 7 k is max and you are worrying about pull to 7 then there is a concern. Also you have a 38.5" tall tire. Hell ya its a truck. If you think that tire and drag racing go together think again. Your thread asked about "pull faster in high gear" Lots to change if you are truly looking for hard charging in top gear. Probably need to know more about your expectations.
