I have a question regarding my mods and what you all think I should be running for fuel pressure and timing.
Here are the mods.
Engine Modifications:
1986 Ford Mustang GT
-Ford E7 Cylinder Heads, Ported and polished with a 5 angle valve job, and Performance Vassco Dual Springs, Moley Keepers and Retainers
-Ported Lower Intake Manifold off of a 1986 Mustang 5.0
-Upper Intake off of a 1993 Ford Mustang 5.0
-Mass Air Conversion
-1/5/8 Jet-Hot Coated Pacesetter Headers
-Kirban Adjustable Fuel Pressure Regulator
-Pacesetter Off Road H-Pipe
-Flowmaster 3 Chamber Exhaust
-65mm Ford Racing Performance Throttle Body and EGR Spacer
-3.55 Rear End Gears
-19 Pound Fuel Injectors
-Ford Motorport 9mm Spark Plug Wires
-MSD Blaster Coil
-Modine 3 Row Radiator
-180 Degree Thermostat
-Pro 5.0 Power Tower Shifter
-140 Amp Powermaster Alternator
-K&N Conical Air Filter
-ARP Head Bolt
I want to know what I should set the fuel pressure at. I know it says to undo the vacuum and then set it and replace the vacuum line. I do not have the sheet on me that tells the specifics, so what do you all run? Second. What should I run for timing? I use 93 octane right now. At what time should one go from 90 to 93 octane as far as timing goes? I have experienced pinging at about 14 degrees, so I think I have it at about 10 right now. I just want to see what you all run if you have a combo comparable to mine. I get 14 mpg in the city and 20 on the highway. This seems low to me. Would 3.55 gears cause my mileage to drop this much? Thanks!
