I have recently installed new Autometer tach and speedo and I through away the 88 Mustang speedo with redline on it. Does anyone know the red line on 1988 5.0 HO?

Thanks,

Redline is 6000rpm but more importantly, the yellowline starts at 4700rpm!!!!! This is where the power fades and you get nothing but noise till 6000rpm.

the EEC-IV computer will shut down the party at 6250 RPM - but if the motor is stock, there isn't any power up that high anyway. Dont trust the stock tach - they are notoriously inaccurate - as much as 500 RPM at the top end during rapid acceleration.
