Correct Holley 4barrel Carb for 1970 383 HP

[DeltaV]

No AC with Fresh Air setup I believe from factory. You will have to notch the air cleaner base. Also you have to have a 3 spd wiper motor

J25: Windshield Wipers, 3-speed-Std. w/383 4-bbl., Super Bee & R/T.

What would be a good chose w/o California emmisions

If you can't find a "correct" carb, for a clone a generic 3310-? (Multiple dash numbers have been made) 750 vacuum sec would be my choice.

If wanting AC you can change the compressor like they did on this car View attachment 1794769

great setup was also going with aftermarket ac

or notch the back of the air cleaner base too,
with the 2 speed wiper motor
it's not a very big '1/4 moon' type notch either

I had to do it with my 1969/70 fresh-air style air cleaner base/for a 6bbl
(with an aftermarket lowdeck MP 6bbl manifold)
on my (not a 1970) 68 RR 383 335hp (org. had a Carter)

or a 770cfm Street Avenger, dual feed, single pump/accel squirter
is a great replacement carb for the Holley 3310 also

Not sure if Im following this right but my 70 Challenger 4 speed 383 HP had the Holley but not the fresh air package. Wasn’t an RT either, a plain Jane car with flat hood
