Holley Carb ID

[Neville W.]

My 66 327/350 C2 coupe that I thought had all the correct parts, seems to be without it's original carb (R3367).
The one on the car is a 4160 series (R80457)with a electric choke. No list number or date code. What would this have been on originally or is it just a replacement?
Eventually I will obtain correct carb but for now I'm thinking of just jetting the thing to factory specs. The car seems to be running quite rich with whatever jets carb has now and secondarys seem to be only half opening (black spring)
What would be the correct jets and are there any gotchas on setting carb up as per factory with this different model?

Thanks
Neville

80457 is a 600 CFM,69 pri jet. 80457-1 uses a 64 pri jet. they both call for the black spring

Re: Holley Carb ID

#69 jet is pretty stout (rich) for a small-block; the original 3367 had #65 primary jets.

The engine certainly feels and smells like it is running rich.
Time to see what is in there methinks.
