First if you have a non roller block you need a flat tappet style cam to make it easy, the cams you list are all ROLLER cams, and they are way to large for the flat piston you have in the motor. You can go roller but you'll need to run link bar style lifters which are in the $400+ range. There are plenty of flat tappet cams out to make great power.

Do you still have stock cylinder heads? The Parker Funnel Web is a serious intake not made for "stock" style motors. The 750cfm carb is also way to large...

I go with a nice dual plane intake, suitable cam and a 650cfm carb...it will make great tq down low and increase the hp over where you currently are.
