Sully, I had a problem with my 70 L78 Nova when driving it. When it would get hot it would stall/shut off. I put the heat shield, GM one pictured above, on and never had a problem again.. I figured it was because the intake and carb. were soo close together it was boiling the fuel in the primary bowl. That shield really does work!!
It does not look that bad either under the carb... Rich
