I think you should call up a couple of cam manufacturers and ask what
they suggest.  Before you call them, have all of the specifications of
the motor, heads, intake (runner size and flow if possible), valves,
valve springs, transmission, and rear gears in hand.  Tell them what
you want the car to be able to do and they should be able to come up
with a cam that will fit your needs.  Most companies have good
customer service lines to help you with your choices.

    You realize that with all those changes and a cam as radical as an
E or F the speed density computer probably can not compensate for the
difference.
