Breaking in a race engine?

I've been doing nothing but worried. I seem to remember being able to floor it from a stop and spin the tires real good. Now I romp it and it will spin them for about twenty feet. Could this be because I took around 100 pounds off the front of the car. Now it's hooking better? With street tires!

Did you have Hoosier QTP tires on before?....because they will hook WAY better than any street tire.

I would not worry too much till after you get a chance to run it and get a time slip...it might be all in your head and the car might run just fine, who knows. Good luck.
