When driving my 1964 1/2 Coupe, there is a strong exhaust / gas smell in the cab. It is worse when the windows are open. Recently had engine work done, and mechanic didn't find anything. Had purple hornies removed and the original chrome put back on. Work included installation of a new hood to cowl seal.
Don't really notice the odor becoming worse when the ventilation is on. Had the vent hoses reattached when the dash was off.
Mechanic did replace a short stretch of hose attached to the fuel filter that was cracked and spraying gas onto the distributor cap.
Any of this sound familiar? Am probably going to take the car to an exhaust specialist to run the system to see if there is a leak underneath. But problem is mainly occuring when the car is in motion.

The solid steel fuel line that runs from the carb to the tank is connected to the tank via a soft line about 2" long.
That soft line is probably leaking and allow gas vapors to enter the cab via the trunk .
You can see this line simply by sliding under the car and finding the fuel pickup.. wiggle the line around and i bet fuel drips out or it completely shears off

an exhaust leak could cause the problem but i bet you would hear that.
yes the soft line is connected directly to the bottom of the fuel tank. It should be in the middle of the tank, on the bottom, and towards the front... you gotta get pretty far under there to see it.

OK. You have me thinking. The car is idling pretty rough. Fall off and slight delay in moving when the gas is applied. Know that can be carb or timing. But again, wondering if has to do with exhaust...
probably noting to do with exhaust....timing more likely or a fowled plug(s), broken plug wire, leaking plug wire, worn points, or worn cap/rotor as well.

I would venture to say you have more than one problem, but one of them is serious enough to be dangerous.
Even if your exhaust smelled like stink bomb, and you were to pour gasoline over the trunk lid, you should smell none of it while driving. The fact that you do smell it tells me the back part of you car is not properly sealed. This is not just unpleasant, the possibility of carbon monoxide poisoning can be deadly.
There are a number of things to check.
Trunk lid seal
Trunk floor and extension plugs
Strip caulk between gas tank and trunk floor
Back up lamp wire plugs
Foam seals between body and bumper brackets
Caulk between quarter extension nuts and body
Foam seals between tail lamps and body
Cork seal between gas filler and body
Gas filler to tank hose
Bumper guard bolt hole caulk
Fuel hose at the lower front of gas tank
Oval caps above shock absorbers
Splits in caulk on floors and panels
Rust holes of any size under car
