check your cam timing, the cam may be out , iv bulit a 350 once and dingdong me wasnt watchn what i was doing, i put the cam in with the timing chain gears and the cam was 1-2 teeth out, and it was doing the very same thing yours is doing so i had to pull it back apart, and boy did it come to life!!!!
