I only have 275/40 though. Only spins in 1st though unless it is cold and I can launch it pretty good. Probably only 11’s on drag radials though, faster than it was when it had 331/s-trim combo. It beat my friends 125+ trap speed LS7 GTO with that old combo.
That Cobra still ran a lot better than many people expected, but that is what a well setup auto trans will do for sure. I think it could use more converter maybe even.
