Damn, you beat me to it Md.

Yeah, mid to low 14 would be my guess. Those 2.77's are really holding you back. With the help of your converter, some 3.42's or 3.45's and good traction you might be able to break into the 13's or at least get very close.

My B4C topped out at 142 MPH stock with the 3.23 gears, but I didn't have enough road to see if it would go faster, and I have a 145 MPH spedo. I believe you should be able to do between 140-150MPH, but you will need a nice road with no traffic. I believe from reading old articles that an L98 equipped F body can do about 147 (someone correct me if wrong).
