what are you going thru the lights at? I'm just hittin 7000 rpm at the finish.rear end is a 4.71.my mile per hour is slower than yours as I have less horsepower. Would like to get the power up a little more and go through the lights closer to 7800. That would bring my mile per hour up to around 134 or so.that will probably take another 50 horse and I'm not sure I can squeeze that out of stock cast iron heads and cast iron intake without spending big bucks.
