Yeah that is weird, maybe its a chevy thing but by more displacement you gain more vaccum you get, I've played around and found this out by buying multiple cams and having different motors to see how much vaccum each motor can pull, thats why mid-states has different vaccum tolerences with a big block and small block cause a big block will have more power than a small block at the same vaccum, That's why I think mid-states has a better system cause they see this and have mad adjustments to the rules to make it a better race and makes it that much more exciting for the fans and drivers!
