89 b2600i stock redline?

my truck doesn't have a stock tach, so i installed a small aftermarket one, and was wondering where the stock redline was?

does anyone have a b2600i with a tach? I've seen plenty b2200s with the 6000 RPM redline, but I'm not sure about the 2.6L engine.

also does this engine have a rev limiter?

thanks

i wouldn't rev a 2600i past 4000, you might crack the head hahahahaha

ya, i'd set it to about 5500 and that's pushin it ahaha.

Just rev it untill it hits the fuel cut off. You will know when that happens. You might blow the damn thing up though.
