Rich Carb

just going by mopar performance reccomendations and past experience adam.think about it adam ,your numbers dont add up.22 plus 23 is 45 degrees total. I disagree , the above procedure is correct and converter has no bearing other wise why would a race car lock in at 1200? its about the added spark advance.so your saying I should set total 38 all in by my launch, which is around 3500 rpms?if so why are the racers locking in their 4500 converters at 1200? added spark advance plain and simple.at 1200 lock in your running around 75% over stock ,yes and that makes the car go faster.the 35 degrees by 2000 to 2500 max is what a hipo street car wants.
