Summit Cam Help/Recommendations

So would it be better to pass on the cam for now and get more work done to the heads? As in get the heads done up really nice with a little more porting, milling, new springs, etc. until it's time for a cam?

I suppose I should elaborate on why this is happening right now too. The car has the original 318 in it right now, but it quite frankly doesn't run good at all and has started to develop a knock. Also, the trans definitely needs a rebuild and the engine bay needs wiring work desperately, so I decided to find another motor to throw together for cheap to get the car driving good again for the summer. A big factor in the small budget is the fact I need to get the trans done too. As luck has it, I found a nice complete 360 for 100 bucks and here we are now. Just figured I would see what all I could do within budget while we have it apart to regasket and check everything over.

Thanks again for all the advice, I really appreciate it!
