First 318 build, cam question

The car is a stock '72 Swinger with a 318 2bbl (not running), 904 trans, power steering, power brakes (front disks), and I believe the rear is a 7 1/4" with a 2.76 gear, but I need to double-check it. I have an old 600cfm Edelbrock 1406, matching air cleaner, and a new Edelbrock Performer intake that will be installed on the engine. I will probably install headers and full dual exhaust, but not until after I get the car running again. I don't know if/when I'll get around to doing any head work or changing the rear differential (I'm planning to do as much as possible myself, and I'm just an amateur with hand tools and a garage). The goal is to make a fun, reliable driver that keeps the power accessories - I'm not planning to race or show this car.

I was looking at cams, and saw the recommended one for this combo is the Edelbrock Performer 2177 (http://www.jegs.com/i/Edelbrock/350/2177/10002/-1) with .420/.420 lift and 270/270 advertised duration.

I ran this same cam/intake/exhaust/rear gear combo in my 74 swinger about 15 years ago and was able to pull high 14's at the track with it. That Edelbrock cam is very mild but makes good torque which is what you'll need if you plan on keeping those 2.76 gears.
