Tach Redline

I just installed a tach in my 84 Ford F150. I need to know what I should set the redline at. It has a 351W and a 4 speed. IT had 258,000km on it, but I feel it has been rebuilt because it has between 140-160 lbs of compression in every cylinder. I do not use the tach to drive the truck, more the sound of the engine, but i want to see that I am shifting at the right time, and it is nice to have it there.

I mounted it under the dash, looks pretty slick, I will post pics later!

Thanks!!!2

i would set it no more then 5000 but because of the higher comp(it should be more in the area of 120-130) you could probably go up to 5500.

BTW it wouldn't happen to be an HO would it?

HO 351 came from the Factory with 4V carbs. most all V-8's use a 5,000RPM redline unless built to run higher RPM's. So I'd agree with it.
