Change from a batch injection to a syncronized sequential was like magic with hiperf cam (236/230 @ 0.050”). Idle become smooth and low rpm drive comfort. For best fuel delivery results the manifold should have equal lenght runners. I have found my old Clifford manifold keeping cyl 3 and 4 leaner than others. I will compensate it by ECU.
