I found that info when I went back over the Wbody store's page on the headers comparision. When you say velocity, I am guessing with the smaller collector, you obviously gain a bit more bottom end on the car and still get a fair amount of top end, not as much as the others with their 3" collector though? And that difference, I am guessing mind you, the amount of extra pressure from the smaller collector helps to build up momentum quicker?
If I am saying that right? Good...... If I am saying that wrong? Just smack me with a fish or something![]()
