hey guys i have a 327 solid lift cam torquer 2 intake dart heads. well i have a edlebrock 800cfm on it aND RECENTLY IT STARTED ACTING UP WHEN IT GETS HOT. WHEN I STOP AT A LIGHT THE CAR WANTS TO DIE BUT AS SOON AS YOU GIVE IT GAS IT RUNS PERFECT. I WAS GOING TO CHECK THE FLOAT LEVEL AND I ALSO HAVE THE KIT THAT HAS DIFF METERING RODS AND JETS I CAN TRY DIFF COMBOS DOES ANYONE HAVE ANY IDEAS AS TO WHAT IT COULD BE AND WHAT JETS AND RODS MIGHT BE GOOD TO START WITH. CAUSE THE CAR RAN OK WITH THIS CARB BEFORE I KNOW IT IS A BIT BIG BUT MY VETTE HAS THE SAME MOTOR AND IT HAS A 780CFM HOLLEY ON IT. ANYWAY I WOULD LIKE TO GET IT RUNNING OK FOR NOW. CAUSE I PLAN TO BUY A DEMON IN SPRING THEY RECOMEND A 650 MIGHTY DEMON FOR MY MOTOR BUT IT IS NOT VACCUME SECONDARYS AND I REALLY DIDNT WANT TO GET MECHANICAL SECONDARYS. ANY HELP OR ADVICE WOULD BE GREAT THANKS
