6-pack intake manifolds

Agreed. Setting the 3X2 6 corner idle is really not that difficult. I have the promax plate on my rear carb. You just use the airbleeds (cover each one) to determine mixture and adjust each corresponding mixture screw on the front and rear carbs after the center carb has been adjusted. 1/2 turn out on the outboards is usually a good starting point. Without the Promax plate you just adjust the front carb and repeat after swapping front and rear carbs. I just set mine and leave it alone.


Between the cost of the sixpack setup and difficulty in tuning it right I get why they are no longer in production.
