At 7,000 rpm and 100 percent VE, you pull 950 cfm with 470 cubes. Your VE may be over that, but not by much. I would think the pv would be plenty high, and your WOT vacuum will be 1.6 or less. Probably the only real test would be a AFR test to see what is going on. You could also put a new 4.5 in it and test it.
