I have a 517 BBF that sees both street and strip duty.
Your build depends highly on budget. If budget alows get a hydraulic roller cam, but that is pricey. If you don't mind adjusting lash a solid roller is a bit cheaper, and cheaper yet is a solid flat, but for a street stripper I would go either hyd-roller or hyd-flat tappet.
I would go for something with 230><245 duration. 110-112 lobe centers. (110 will give you a nice lope ) Higher lift hyd-flat cams can be difficult to get in the block. My Erson cam with .545 lift was a pain to get in the block.

For dual purpose cars, it is hard to beat Edelbrocks air-gap intake manifolds.
But with the big blocks, making torque isn't an issue (its hard not to make one of these motor not torquey) so you could go with a Victor single plane.

For carbs, it is up to personal preference. I am running a modified 750 vac secondaries on my car, most would scream that this carb is too small, but I love the super crisp throttle response it gives me! I have modified it with a Pro-Form main body, quick change secondary spring kit, and a secondary metering block. For max power I should go with probably a 950-1000 CFM unit.

Hope this helps a bit,

Joe
