Dude, what the hell is wrong with you? Why do you continue to ask this same question over and over? What do you expect to see from a video? My car makes 660 rwhp with a Novi 2000 and a 302 stroker, and it has 4.10's. It is my daily driver. This weekend, I drove it 550 miles from Atlanta to Richmond, VA, qualified 1st in Mod Motor (FFW), and then drove 550 miles back to Atlanta. I got over 16 miles per gallon with a 3800 stall converter. I usually cruise around 70 mph at 2700 rpm. What more can I say? Get the freaking 4.10's and move on. If you worry this much about this simple question, heaven help us when you start debating which power adder to get.
