Help me decide!

I have a stock 2bbl 318 in my 73 Dart, it has a 8 1/4 rear (with stock ratio's) and a 904 trans.

Intended use is street, A lot of around town driving and the ocasional 1-2 hour highway cruise.

What should I put together to create the best street/Daily Dart (don't mistake daily for mild!)

I intend to put an Edelbrock 600cfm on all of this, or can I go bigger with a different cam?

Which intake of the following, I can get both cheap, the Edelbrock does cost 4x's the 360 though:

Elelbrock performer 4bbl intake

Stock 360 dual plane 4bbl intake (the Quadrajet type)


Cam options:

Stock 340 (in excellent condition) cam with new lifters 100,-

Edelbrock performer (all new) 160.-

Used 360 cam and lifters 120,-

The engine has hooker performance headers and a dual exhaust. I'm keeping the heads stock. I'll be running a 600cfm carb, bigger if possible but I think 600 should suffice.

What's the best option to improve spark btw? Mallory electronic ignition? I don't think an MSD setup is necessary for my application...

Looking forward to your ideas on this, I'd like to pick up the parts tomorrow and have it done by the weekend :)
