Cam up my 318, help me chose!

Rusty is right. Gears would be my first choice also. -Camshaft selection is pretty much married to compression, and stock 318s dont have much of it. If you cam it up without a corresponding C/R change, you will trade away a bunch of bottom end torque for a very little bit of top end power. But since you have 2.76s, you barely get into the powerband at 60mph, and because of the torque loss,it takes forever to get there. -And spinning one of two tires, however far, is hardly grounds for bragging.
WHO bragged about spinning one tire?? If your referring to my post, I wasn't bragging, simply made a statement that's fact. If you read my entire post, it is about doing good with what you have. One has to compare apples to apples. I was also implying that one has to have a performance level that they would "be happy" at when building a motor. My point within my point was also that your car needs to be achieving what it should before moving on. For example, if something is severely wrong now, yes gears would help. But that's a false improvement. Get the issues fixed now so you can get the full benefit of the whole package, gears, stall, engine.
