I can drop the clutch at idle & it will smoke the tires if not controlled & i can cruise in traffic @ 1500RPM in 4th very nicely. I am definetely not a carb expert but it would seem the carb you are recomending would be a little small for a "460 with a big cam"

The street Avenger series of carbs is like using an Edelbrock carb on a performance engine, used strictly as a plug and play item good for street cruising at low only.....Too large a carb and you create issues with washing the cylinder walls down with fuel, mix enough fuel with oil and things go boom. A simple formula is attached below. As for your carb, just because it says it's a 950HP does not mean the main body, idle curcuits, jetting, and squirters are sized for 950cfm. I'm assuming someone set up your carb to your engine? if not, I'll bet you I can make more HP with a smaller carb on that engine thanb what you have on it right now as it sits. Bold statement, but I can back it up with both big block and small block stroker experience on a chassis dyno.........Not an engine dyno, but a chassis dyno.......If your's is working flawlessly, then you are one of the very lucky few, count your blessings.........
