Have a 750 edelbrock carb on my 454 in my 81 malibu. Car has a wide ratio muncie with 3.25 rear gear and 28 inch M/T tires. Car runs good, idles fine, pulls hard, however when i rev the engine and dump the clutch for a quick start the car just dies. I have had the timing on ported vaccum, manifold vaccum, adjusted the floats, installed fuel pressure regulator set at 5 psi, idle speed etc. and car continues to stall. Initial timing is 14 with total at 38 all in by about 2,800rpm. I did remove weight from the secondary air valve, would this possibly cause this to happen? It's driving me nuts?
