Question Is this good???

I bought a 460 out of a 74 Mark IV. And I put it in my Bronco. The mud bog I run at checks for vacuum for street class. My motor checked in at 19 or 20 on the guage. Is this good??
As far as I know, pretty stock motor, sat for a couple years, and I believe had around 65,000 to 70,000 miles on the car.

Carb/Cam. We have to be able to pull 15 here with our pulling trucks. What I did was found the carb I wanted (It happened to be a holley 850) and then I called the people at Comp Cams and told them exactly what I needed. I told them what I had done to my engine and heads and what I planned to do with the truck and what I needed to pull on the vacuum. I didn't pay that much more for the custom cam, maybe $75. But When I put it all together I got right at 15. They did the same thing with my buddy's Dodge.

20" of vac us considered about perfect for the typical good running, good tune and shape stock engine so yes that is good.
