I need to work on the cruise afr to start in my 3 circuit holley 80532-1 carbs[1250cfm]x2 I am testing at 14# because idk how low [8#] would effect the afr with flow through the carbs.Currently stepping into the gas slow gets me 13 low rpm to 14.4 at lets say 4500 rpm so I think I need to close some of the emulsion jets li 2 of the 5 [.025 size] I have mufflers,street tires,Insureance but testing is still risky on the street as you may understand .I am working on an electrical issue/reliabillity so I can test at the track t&t.I get on the gas at 1:24 sec into the video.
Nice.....I am building somthing very similar, and I hope mine runs as well as yours. You don't even seem to have the blower lope most do...Very smooth driving....
Mine is also 446 cubes, but with an OEM block and I will be ordering the 8-71 soon from TBS. It was built by a friend of mine that ran it on E85 with an 8-71....How did you come to using two 1250 Dominators? I have a pair of 750's I am going to try. And no boost refrencing?

Boost reference is for blow through applications only. In a draw through there is no pressure on the float bowl. In a blow through the float bowls also see boost, you have to raise the fuel pressure at the 1:1 ratio so the carb works as normal, otherwise the fuel gets forced back into the lines.

Thank you for liking my car! I started with 850's 20yrs ago and my top goal of 20# after I got a Koleno block the cfm requirements went up and blowers don't like restriction so I got as big as I felt I could deal with and on the dyno I lost 100*F from bigger carbs. Setting up the carbs to start and have the least lope takes some time testing what pump shot it takes and how rough it runs getting it warmed up and turns out to be 12.5 afr at idle cold and it warms to about 13.5 and when warmed up the lope starts at 13/1 afr.
I take it you run pump gas? What is target AFR for WOT? And what is your max boost?
No I have run sunoco/VP 110 from the beginning and afr12.or a little lower 11.5 full timing at 34* 9/1 cr 14# for the last 17yrs. with factory iron heads to start and then Edel Victor std pot now,.631 lift 260 dur at .050 112 lsa

Cool....I might bug you later...so much to learn on these boosted setups...Shooting to start at #10 on mine and land around #15 later....Guy I bought it off of, said it has seen #22.....But it was too hairy to drive....
