340 Build advice needed!

ok, here it is, standard stroke mopar forged crank, eagle rods, forged trw float pin flat top pistons 30 over, i have j-heads mild porting with fresh valve job, so basically a stock 340, im planning on getting headers and using a holly 650 dp, the car i have is a 4-speed and i want to run 3.73 gears, a good streetable motor with plenty of power that ocasionally may hit the strip......what i need to know is what intake and what cam to go with, ive been all over the place trying to decide, but since the bottom end needed work ive been looking at the comp cam complete kits since i need all of the components anyway (springs, retainers, locks, timing setup, cam and lifters)...........opinions or advice???? thanks
