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.
i tried the 1.7 rockers way back when my 91 was almost stock you will not hear much of any difference the b303 has a noticale idle and the x303 sounds aggressive but you realy need to do some head and intake work or replacement
well the thing is im only 16 and i dont have a ton of money so its kinda hard to do head wwork and stuff..... the main thing im concerned about right now is how it sounds....when i get alittle more money saved up ill do head work and other expenive things...
The problem is that by putting in a big cool sounding cam on an otherwise stock motor you will lose alot power down low. Big cams shift the power band higher in the RPM range and without the supporting mods, like heads/intake/gears/stall, you will not be able to take advantage of the power gain.
