I really don't know. 408ci 9.5:1, indybrock heads, .242@ .050" solid roller. It went 112MPH in the quarter granny shifting and it weighed 3535lbs right after the pass. It does have power robbing dynomax turbo mufflers on it. I feel like they are killing the car. I started it up with open headers not long ago and it wouldn't even idle it was so lean! Hooked exhaust back up and it was back to normal.
