My best at Bfield is 11.03 with my 331. My wheels stay ALLOT closer to the ground than your friends. His 351 obviously has a ton more torque and HP than I do at the moment. New motor will not be done by the spring. I will barely make the closed event at the end of July at Sears. Since I don't ( and will never have) a full cage , 10.50 will be the limit. Putting a full cage in a real 66 GT350 hurts the value too much. My ego doesn't care what the dial in is. The 9.99 ET thing is just about a stock body , no subframe connectors , no mini tubs , no additional/different traction bars , etc. thing. Near total stealth except for the 10" Goodyears. Just "my" preference.
