1/4 mile rpm?

It's kinda hard to say what your RPM is gonna be, since we don't know your MPH is.

Going in the reverse direction, taking your max RPM you are chipped at now of 6200, will give you 113MPH. This is theoretical, it does not account for converter slippage, nor does it mean you will pull 6200 going out the back door.

It would also help to know the rest of your combination.

I would not worry too much about it, stand on it in the 1/4, you'll eather hit the chip or not. If you do, you have 3 choices, taller tire, different gears (like 4.30's, or 4.10's), or put in a different chip for more RPM. Choice is yours.
