Exclamation Holly carb problems

I got my car running well with the 600 cfm now and after driving it for about a month i'm noticing some problems.

When I make a sharp left or right turn i'm guessing the float gets moved up and dont let in any fuel, making the engine run lean. So far this is a real problem for me since I like to scca autocross and i'll be dead in every turn.

I saw racing beat has a cure for this problem but i'm not going to spend what they want.

I was wondering if the downdraft webbers have this problem?

No, the problem is unique to the holley. You can get some center-hung floats (buy the kit from summit, jegs, etc) but the problem is native to a holley. When you turn left, all the fuel takes the crossover tube to overfill the secondary bowl and leave your primaries dry. The two-barrels don't have the same problem.

Like Crit said, if you go with the center hung fuel bowls, that will help alot.
