5.0 HO rebuilt short block from an 89 Mustang GT. Weiand Stealth Intake, Trick Flow Twisted Wedge heads, stock 5.0 cam, 1.7 ratio Crane roller rockers, Edelbrock 600 CFM carb, headers...
How should this engine idle/run? Guesses? My 289 ran ok, but pretty crappy before taking it out. This engine fires right up, but there seems to be some roughness at idle, kind of a lopey rocking back and forth which kind of shakes the car a little bit. I have timing set at 12 degrees BTDC, double checked firing order and spark plug routing, double checked roller rocker valve lash...
I guess I just don't know how it "should" be running.
Help.
