5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
"hyperpathetic" pistons are fine as long as you dont plan on running 15psi on the motor. They are really not that big of a deal if its just a street car.
If you try running a 150 shot or 15psi on hyper pistons you will have problems. You can safely run 10-12 psi on hyper"pathetic" pistons. They are fine for a street car.

Were these there pistons named pathetic for a reason? [sm=alcoholic.gif]
When I was looking for a 5.0, I was only looking at the '91-'93 5.0's. I like those years best because of the pony wheels and I like the steering wheel better then the '87-'89 steering wheel.
