pretty simple: trunk seal not sealing.
when driving, exhaust fumes get trapped in a turbulance behind the car. with open windows, you get a low pressure condition inside the car = exhaust fumes get sucked inside through the "leaking" trunk gasket.
i agree , i have the same probalem with my car , it needs a trunk seal

Where does your exhaust end? Does it go all the way out back beyond the bumper or rear valance, or does it end in front of the rear axle? A buddy has the same problem with his AAR with the stock side exit exhaust. When he is stopped and at idle, the fumes come up thru the side glass when the windows are down. OOPS I just noticed you said the fumes under the hood were really bad when you were working on it. The change to the bigger cam may have you running a lot richer than before. Have you checked the plugs to see if it is too rich.

Exhaust comes out to rear of bumper about 1/2" past the bumper and I pulled a plug a week ago and it looked good. The post of the plug was slightly brown. But I will check the body plugs. Anyone else??
ummmm.....let me think.... TRUNK SEAL

I had this problem too. The car also ran hot. Problem, not enough initial timing and too lean. is your intake mnfld a single or dual plane? what is the overlap of the cam? A lean misfire cannot be heard or felt, but puts out more HC than runing rich.
