6k? Are you high? Even under optimal circumstances you shouldn't shift a fox stock block above 5500. The harmonics from overspinning the motor is what kills the block when it splits right down the valley.
Add to that a blower pulling on the front crank pulley and a FMU for fuel management, spinning it that high is just asking for a blown motor. Using a FMU is like putting a Band-Aid on AIDS. Pointless. It's just there to barely make the car run and certainly not something that should be used as a source of reliability.
My 93 Cobra made over 500rw on the stock block for over 5 years. With a solid tune, a chip and 42lb injectors, it idled good considering the size of the large cam. The reason it will still running like a champ when I sold it was because I didn't beat the snot out of it and I didn't rev it above 5500rpm. I rarely drove it hard at all knowing the motor was on borrowed time.
