Thank for the replys. I know the Blue pump will most likely work, but I think I'm just going to add a Carter mechanical. Its $60 vs $200+ for pump and regulator not including having to re-plumb. It's the simpliest, cleanest looking and cheapest approach. BTW,
Chuck, I have too much into this engine to let it go lean on me. I need to protect my investment and 120 gph should be enough for street driving and occasional open track. I talked to Keith Craft about the Red pump and he felt it is marginal at best and be careful it you ever jump on it. If you are running a stroked 427 with the Red pump, I urge you again to look at the flow curve for this pump on the Holley site. If you are running about 3-4 psi, you will be ok, but if you are running 6 psi (which I think is about norm), you only get about 20 gph (not a typo).
BiB, the Blue pump comes with a requlator from Holley. If you paid for a Blue pump and the builder didn't install it, he owes you a regulator.
