Brian man no wheelie bars running that kind of times I have seen some cars running way slower then that and get way up in the air if they don't spin and tear there oil pan up.I got wheelie bars on mine and I have just gone 7.25 just in case I need them. Well anyway it sure looked good on the track. I hope the 454-r gets you another tenth I was off on my guess by .06 thats a lot. But I can say I gave it my best shot. Stay with it you will see some 80's.
