Its Time To Build Some BOOST!

That's great your making progress Bill keep at it. I have a concern about you running the other carb with the stock PV. The stock PV is only good to run around 12 psi of boost and after that the boost pressure and the increased fuel pressure seen in the fuel bowls forces the stock PV closed and if it happens while your under load bad things can happen
Just my 2 cents Bill all info given is strictly from what I've read from real world experience
