I am going to try two Autolite / Motorcraft 2 V carbs and also a couple of 2 V Holley's

I am still hunting for a project car to build but with my current low budget it's not looking so good. My Ex- Fleet of Sixes these are all long gone! :bang: 1954 Customline 223 3 speed with O/D, 1963 Fairlane project drag car with BB6, 1977 Maverick 250 with C4, 1994 F-150 a 300 with 5 speed.

Try two Autolites:

If you want it to pull to 6000+ I'd try two 1.21s.

I would favor 2 Holley 2300s, smaller up to 350 cfm size. If ya can find a matched pair? the ones used on late 50s-60s Ford Cars/Trucks & 60s-70s IHC stuff are small. But might be a pain to find ? Prob. easier to Get 2 Race Bowled 350cfm Holleys. :nod: 2 Autolite 2V Carbs. should work fine 1.21 & smaller,(If ya gonna have it on the Street) would be my guess? :hmmm: If your Car is light ( 2500 lbs.?), you might be good with a bit larger?, on the Drag strip.
