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.
ok i have a typhoon intake, on the car and it has i think summit shorties. i need to know what headers work on gt40p's thats all. if it more to get the gt40's worked and new headers then i will be one of your guinea pigs for the patriot perf. heads.
Most will work, the P's just have spark plug clearance issues with some headers
Like said above, the Ford Racing headers should give you the clearance you need.
How about this monkey wrench in the machine. 66 mustang, with a 69 351w short deck, with a set of gt40p heads mated to a c4. Anybody played around with this combo. Im just awaiting the arrival of my 1515 bbk headers. And heres another thing, how come some advertise the 1515 headers as equal and others as unequal. What am I missing there?
