rebuilt 318 ignition cuts out

hi all, i recently rebuilt a 318 la with a slightly mild ish cam (441 lift) 360 heads, 4 bbl intake edelbrock 1406 carb and a points ignition, the car is a 65 barracuda, anyways when i rev the engine to about 3k rpms, it cuts out like its got a rev limiter, doesnt shut off or anything, happens no matter where i time it, i have the points set to .20, tried 3 coils changed the points nothing seems to change, everything for the ignition system is pretty much stock, any advice would be nice thanks
Condensor changed also?
Excessive shaft play ?

What are the timing settings?
