3000 seems about right. Mine redlines at 3100. Always has.
I've seen factory tachs in the 1980 to 86 trucks with our 300, with a 3000 max reading, just like the diesels have.
I've also seen the 300 with the 6000 max tach too. Weird eh?

My 86 F150, 4x4, np435, is a beater. Basic rattletrap. Pulls 4000rpm, but then mines broken in. Yours only has 200K on it.
I yanked the carpet after going through some high water. It's drying out under the Baja sun. I guess I should go back and get it. Might help with all that noise when I hit 4000rmp.

I have spun my 300 to 5000 rpm several times without grenading it. I don't drive it that way. I usually shift @ ~ 2500-3000 rpm. I shift high due to the huge gaps between gear changes in my NP435.

You guys need to get rid of those ugly "Sunpro" tachs and get a real tach, Autometer. Or even better, the factory one! DUH!
I've had my EFI-6 up to 4500RPM with the OEM tach.3000RPM IS NOT redline although it may seem like it, hah.
