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.
Dude, just change your thermostat out. I couldn't fathom trying to put headers on your car just to make it run hotter, unless you are using it as an excuse to shell out the bucks for headers.
ok, i needed new headers anyway so i bought those. When i install them hopefully they will let some more heat out back in the engine bay because this 160 is not healthy.
What is it you don't understand when several people tell you to change the thermostat back to the stock 190 one??????
I'm confused to say the least![>:]
