Thanks Carbking for the link to the carburetorshop. I read it and do agree with the cautions on installing an electric pump. Shamefully admitting I have no experience in carburetors, I felt that if Holley says the pressure has to be at 6 to 6.5 psi then I should start with that. But okay then. I'll keep my low pressure mechanical pump, leave the electric pump out of the equation, and see if I can get some help on fine tuning the Holley. But, can I ask, if my engine is running fine once I shift into 3rd, 4th, and 5th with normal demand on the engine (city streets, no hills or freeway entrance) , but is always cutting out when accelerating on normal takeoff in 1st and 2nd, where would you start as far as adjustments on the carburetor? I haven't got as far as testing on any hills in the area or trying to get on the freeway. I really appreciate all the help provided by this forum. Thank you for your time.
