New cam for my 318

I'm going to run this by everyone here, because I am by no means a cam expert; I'm just some dude who loves Mopars and is mechanically inclined.
My 318 was replaced about 12 years ago after the last one finally gave up the ghost on me on the highway. When I put the "new" one in (I got a rebuilt crate engine from a local auto shop) I added the following aftermarket goodies:
1) Edelbrock Performer dual plane aluminum intake
2) Edelbrock Performer 600 cfm carburetor
3) Mopar electronic ignition
4) dual exhaust - 2.25 inch, no cross-pipe, stock manifolds

So that is where I am today. The car sat for about 7 years, but I have gotten her back to road-worthy. Now I am itching for something exciting to do - so I thought, why not drop in a different cam?
I found this setup on summit's website: it's part# cca-k20-221-3 if the link doesn't work...

Remember, I am looking for something to compliment what I have already. I am running stock heads, a stock 904 auto-tranny, and a stock 2.76 geared 7 1/4 inch rear end. I have no desire to replace the tranny or rear end soon, and heads are a maybe. I'm looking to pick up some pep, without sacrificing my limbs or children at the gas pump.

Anyway, what are your thoughts? Would I notice a difference with this cam? Is there some other place I should be spending my $400-500 right now? Would this turn my engine into a transmission and rear end destroying beast?

Thanks in advance everyone. I look forward to reading the replies!
