Let me get this straight, and I don't mean to sound adversarial because I truelly enjoy reading and contributing here, but none of you have ever run a clifford manifold, let alone one with a 390, 450 or any other carb and you want to theoretically opine that no matter what, it will not work work or run well? I ran one with a 390 carb and it ran great. Could I have run a bigger carb, I guess but Jack Clifford (late 70s early 80s) told me that the 390 was the right carb for that manifold and that anything larger was too much. I used what he recommended and after a little bit of basic holley tuning, it was a very good set up.
How is it that those who have never actually run one of those intakes can be so insistant on poo pooing an induction system they have never ever used themselves?
I don’t see why the little Holley wouldn’t work fine on the primaries. And I appreciate that you can speak to it first hand.
Did it ever need the secondaries? And if so, how did you tune them?
