alright after driving it around quite a bit, and cruising to the beaumont cruise. I am unsatisfied with the power. I got 10.3 mpg with some town driving and to and from the cruise. I think that the mileage isnt gonna be to much worse than the 351.
So on to what i need to do to the 460 from big nasty to put it in this bronco, so i would like some help from the motor guru's. Also this is gonna stay a carb so if efi swap is what you have in mind then this isnt the post for you.
What big nasty's motor has
huge cam i think this is the cam i used i am away from my house and dont have the cam card with me-

straight up timing gear set to get rid of the factory retard
bored .030 over
factory pistons i believe
stock intake
1 inch carb spacer
k&N
motorcraft two barrel carb i think it is a 500 or 550cfm it is the motorcraft one that is so good, and most people like maybe 5125 model number?
truck's exhaust is stock manifolds to a 3 inch system with a flowmast 80 series i believe
msd blaster coil
Bad/things that need to change:
The cam has a power range that is 2000-6000 which is way to much for a street driver it took all of the ass out of the motor at low rpms and take off. It also robbed all of the vacuum from my brakes which is not an option on this truck. It sounds bad ass though(thanks highschool friends dad who helped me pick it out(who coincidentally built stock cars).
Needs a aftermarket intake
I am also gonna do some dremel work on the exhuast ports on the heads to remove some of the casting pieces and what not that these motors had.
Change carb
I would like some help picking out a cam and intake like i said 85 percent of this trucks life will be on the street. I have a brand new stock cam but would like something to compliment the intake and give a little more power.

i am kind at a loss at picking a cam since it has been so long since i did my 460 research knowledge, should i just get a matched cam/intake combo?
Carbs-
the motorcraft ran great off-road but is starving the motor.
i have an edelbrock performer 1406 600cfm that came off a parts truck that i will prolly rebuild and put on there, and i have a q-jet also but i am leaning towards the edelbrock. I am open to other carb options
so give me any info or help you gots.
