Sounds fair, do you have a 1/4 strip near by?

 

You can calculate your approximate 1/4 mile time based on using your 1/8 mile time and speed: Wallace Racing - 1/8th Stats to 1/4 Stats Calculator

 

No 1/4 mile track. So does numbers sound right? Right now its running a street tune on 93. Is there any room for improvement according to mods? If so how? Motor is making aproximately 450hp.

 

It don't sound bad, I'd take it to the track and run it..
