Chevrolet Repair: 1969 Camaro Stalls, lincoln mark vii, 1969 camaro

Question
I have a 1969 Camaro with a 350 and an Edlebrock 4-barrel. Every time I turn to the left the car stalls. What could cause this?

Answer
I have a Lincoln Mark VII.  My sister owned it prior.  When she owned it, the gas tank rusted and my dad bought her a new "discount" one.  I installed it.  Now when it gets to 1/2 tank, the fuel slings to one side of the tank on right turns and the car stalls.  If you have a fuel cell this could be the same thing for you.  If not, check the fuel bowl and float.  The same thing could be happening inside the float bowl.  

Hope this helps.
