According to Jim Schild's book, in 1970 the center carb was different depending if you had an automatic or 4 speed tranny.
R4375A - 4 speed carb
R4376A - automatic carb
R4383A - rear carb
R4382A - front carb
What was the difference on the center carbs?
What exactly is holley reproducing today for the 440 six pack setup?
My Challenger that I will be installing this on is a 4 speed car.
Thanks, Rob
Holley made more than those two List # for both 1970 CA and non CA six pack cars, according to Holley master parts catalog
I remember seeing 3 or 4 more center carb List #s. Dang the EPA anyways
Mopar had Holley reproduce the 1971 non CA automatic six pack carbs is what I remember now
They will have a -1 after the List number on those later carbs
