something is wrong!?

My first guess, the converter is not right. Front suspension may be holding it back as well.

The car leaves soft. 1.52 at that weight with 550hp it should be 1.40 or better if the car worked right. There are cars with 475hp, sporting low 1.40 60's and running roughly the same et/mph in the 1/8 at 3350 pounds. Brian's (OU812) car with the car craft build ran those numbers.

If everything was right, the car should be running 10.30ish at 128-129.
