"I do not consider jet changes as differing much from "out of the box""

Maybe not for you Tom, but anything I do besides bolt it on is a mod for me , although a simple jet change is highly acceptable, been there, and can now dabble in other areas thanks to your thread here.

After jets the only reason I ever dove into a Holley was to rebuild it, and the jet change was for someone else, I always used the 780 CFM vac 2nds right out of the box, worked great.

OK, so an accurate statement would be, with a simple jet change the 8156 would be a perfect carb for any moderate to high performance street 350-455, given the CFM requirements were not exceeded?

If so from what I have read (Tuner) and the information you have given here, one would think it would be a highly desirable carb, being that you have mentioned the newer 4779 is lacking in design.

Lacking only in TOO MANY COOKS IN THE KITCHEN WHEN THE 4 CORNER IDLE 4779-6 AND LATER 4779 DPs WERE CREATED.

But you are spot on as usual.

LOL

Thanks Tom, in lieu of lacking, perhaps a more accurate statement along with your description would have been over designed.

Furthermore, from Kens signature "Good Ideas Are Often Found Abandoned In The Dust Of Procrastination" on the other hand over baked!

I would venture to say that if Mr Ken Crocie were to reintroduce the 8156, there would be considerable interest, not only from the Pontiac crowd but many others due to this burnt product.
