Might be wrong but the only 383 engine that used a Holly was the 70 all the others AFB-AVS. 2 cams low performance and high performance + 6 barrel type, same specs just different lobe angle. Each engine each year shared the same head just springs where different, (67 had different ex valve size LP to HP) Chrysler did some stupid things but they did keep it simple on this stuff. Way to many 383 Hemi six-packs out there.[/quote]


No,I looked up the numbers on my Holley in the little white numbers books I have and it comes back as a 69 383 4bbl(with a note 570cfm).
I THINK that big block cars with air used the Holley carbs.
Because most every 69 383 w A/C I have looked at had duel snorkel air cleaner and Holley carb. So my car DID org have a Holley, but WHY it did, I do not know I can only guess, the above reason.
