Carb for autocrossing?
I'm trying to prep my 69 camaro for auto-x.
I have a 383 with a holley street avenger 750. Currently this carb will stall if I brake really hard or corner hard.
Does anyone have any recommendations for a carb for racing?????

Try using jet extensions, they'll keep ya in the fuel when it sloshes for and aft. If that does'nt work you can try an off roading 4x4 type carb.....if all else fails, efi!

Dont get extensions as they will lean you out on braking. I am not sure what the offroad carbs have? If you are running out of fuel on braking (stop the car hard and let it die, then look at the plugs) then a 4 corner idle circuit would help. If its dying from too much fuel try a hose going from your front to your rear vent tubes with a hole on the top of the hose. That keeps fuel out of the engine (usually) Baffled float bowls are available as well for corners. I also wonder if your fuel pump is up to the job. If it dies on hard braking after a while of WOT then you may not have enough fuel left in the bowls and then it slams forward away from the idle circuit. Lateral fuel slosh is not usually noticed until cornering forces get pretty high (not sure where your car is at though).
Good luck.
