429 CID in a FOX body - 1050CFM jetting.

http://www.holley.com/data/TechService/Technical/Carb%20Numerical%20Listing.pdf Try close to stock. Hope you have the list# on the Carb? You should be close with the factory jets. Factor in the av. gas as needed. I think it burns alittle faster, but maybe mistaken. Someone will have more info on this I am sure.

They all recommend going up considerably on jet size, like 10% due to its lower mass - density compared to regular gasoline. I have used it over the years with reasonable results.

I have run a little Blue gas, and I mean a very little, as it was semi hard to get. I was always told to add a little ATF, because it burns dry compared to normal gas. 10% cushion rich sounds like a safe starting point and go from there. I stick to my statement of starting with factory jetting and going from there with norminal gasoline. Problem is they don't make it anymore at most pumps, as most or it is cut 10% alky now. If you run Race Gas it burns different also. The link from Holley is for old gas but is pretty close anyway. You will just have to experiment with your combination to see what works best. If you are going to run N20 I would not run Av gas with ATF as the oil may premote detonation, at least in theory.
