teamI was expecting a little more from the terminator. Do you have any average numbers from say, 4000-7200?

-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.
Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

66belairCould you tell us a little more about your combo? What cam is in this motor. That's a bad ass 407. What stroke is it. I know that's a dumb question but lots of ways to come up with cubic inches.
