Has anyone ran this combo and what are your thoughts down the 1/4 mile. lazy?I will be hitting the strip a few more times this year but still enjoy driving the car on the street. it will have a 3k converter and transbrake Edited 19/03/13 08:58 AM by tonyv Link to comment Share on other sites More sharing options...
