Does Anyone Have An Idea More Or Less What My Car Should Run At The 1/4 Mile And At What Rpm Should I Be Able To Stall It At. I Would Appreciate Any Info U Can Provide. Thanks.

 

faster than 13.5

 

should be in the 12's but gotta run it to know. Running around telling people what you think it runs without actually running at the track is gay. Mustang guys do that.

 

It also generally leads to false hopes and a complete let down when you actually do race.
Take her to the track and get some seat time, you'll see your times drop
as you learn more and more about how the car reacts on sticky sufaces.
