Hi, after rebuilding my engine, stroking to 347 and top end kit, will it be neccessary to change anything else right away, injectors, fuel delivery, I am switching to mass air as it is an 88. Still has stock fuel pressure regulator and 19lb stock injectors.. I have done some basic upgrades, cold air intake, underdrive pulleys, alt. electric fan, headers, x pipe, but haven't touched the fuel delivery etc. Should I put 24lbs in
