1992 ford ranger question

Whats the rev limit on a 1992 ford ranger 3.0 liter engine....I got my tach set at 4500 but i heard somwhere it redlines at 5500....Just want to make sure so i dont blow my engine

I was also wondering if this truck has a fuel shutoff switch that activates when the revs get to a certian point

C'mon...doesnt anyone know?

on my 94 4.0L mine redlines at 5K
now if i have the clutch in and floor it it will go to 6K and i let off of it but if i dump the clutch the computer does not let it go over 5K untill both tires grip then it will keep on going in the red line but it starts missing in red line
