Hello All,
87 LX 5.0
306 fully balanced
BBK fuel pump
BBK adjustable fuel pressure regulator
19lb Ford Injectors
Cobra upper and lower intake-ported & polished
Ford Racing E303 cam
Truck E7 heads ported and polished
1.7 roller rockers
MSD cap & rotor
BWD performance ICM
Ford Racing Wires
Rotorcraft Copper plugs gap 0.44

I'll describe my problem and then follow up with what all I have done to my car.
When accelerating hard above 3000rpm my engine will act like it misses. It feels like a power loss, as if it wasn't getting fuel. Once it drops to lower rpms it stops completely.
I initially thought it was a fuel issue. I checked my fuel and my pump was putting out 40lbs of pressure. But my regulator was not working properly. So I replaced with BBK 1706 adjustable fuel pressure regulator.
After that...thought spark..replaced plugs with with motorcraft listed above.
I'm now unsure as to what the issue is...do I need bigger injectors? Is my PCM not making the necessary adjustments at those rpms because of the camshaft?
Can anyone help?
