Yes.

IF THEY WILL FIT:

Transfer the primary venturii clusters, the primary jets, the secondary jets, the step-up springs, the step-up rods, and especially the auxiliary air valve from a genuine Pontiac 326 HO carb; and it will run fairly well until it starts leaking from porosity.

Thanks Jon. I have a 4034 ‘66 carb that I could build
Is a 750 AVS a better choice?
