APD “billet” alcohol carb. 4150 body, “1000 cfm”.
http://www.apdracing.com/billet-enforcer.htmlCurrently running in my Daytona.
I bought this carb in the fall of 2020 and really like the way it runs. So I plan to keep using it in the 572 CID B1 engine.
Being a 4150 carb, it has 1.75” throttle bores, and I am guessing 1.56” venturi to get the “1000 cfm” rating from APD. It has slotted mounting holes so it bolts to both 4150 and 4500 intake manifolds. On a 4500 manifold, a small spacer is needed to allow the accelerator pumps to clear the manifold. Plus I think it helps cover the big 4500 manifold opening and good gasket sealing.
This is the carb’s factory setup, and how I am running it in my current 496 CID, 452 iron headed Daytona engine. It starts good, idles nice, great throttle response, and I have not even changed jets it runs so good! LOL
