I am unfamiliar with the Offy 3X1 intake so forgive me if this is an obviously stupid question. What Carbs are you running (singles yes, but which ones)? I see you say you will have the Offy 3X1 and a Carter Electric pump, but (unless I missed it) I don't see where you state what carbs you are using. I don't know for sure, but it is my understanding the BXOV Strombergs tolerate less fuel pressure than the Rochesters, I don't know about the Carters or the Zeniths.
If you want to know if that's too much pressure, I would expect that's need to know info. But maybe I'm goofy.
IMHO an electric pump is fine, as long as you run an oil pressure safety switch with it. A pressure gauge is definitely handy and a pressure regulator, if necessary. But that's me.
