I recently put a 350 with a holley 670 S/A in my camaro. Whenever i try and slow down quickly, the RPMs go down below 500 and it seems like its going to stall. When at rest the idle goes right back up. Recently when i slowed down and turned sharply, the car stalled. What causes this? Can it be fixed? Thanks

Check your float levels. The SA should have sight plugs in the float bowls, the level should be just barely at the bottom of the sight. Most likely yours are too high.
