Intake suggestions

Just a quick update on the carb recommendation. I didnt give the right carb part #. It is a RQ-850 Quick Fuel. It looks to be even more expensive then I originally thought it to be. Is this over kill and how streetable will that carb be? Other choices?
Thanks Rod

I've had great luck with quick fuel products and an 850 would not be overkill. As far as streetable, you took that out of the equation when you installed a 262 degree @ .050 .575 lift solid roller cam and a 4000 stall converter and 3.91 gears. It's gonna be a nasty idling cantankerous beast no matter what carb you put on it. The 850 will be fine if tuned right but that's the trick. By your asking if it'll be streetable it tells me you know very little about tuning a carb (no insult intended) so you'll need to find someone that can tune it for you. One thing I like about the QF cars is each circuit is completely tunable but you have to know your way around carbs real good and preferably have a wide band O2 setup installed.

BTW: I ran a 830 annular on my very mild 408 and it ran great with very little tuning. Only reason I took it off is I drive the car quite a bit and the fuel mileage sucked big time. If my mild little 408 can handle an 830 yours will be fine with an 850
