Hey everybody, first post here. I'm at a loss and I figured you Fox body peeps could point me in the right direction.
First off, I'm no mechanical noob. My daily drivers are a 1999 F150 that I successfully swapped a 6.8 V10 into & a 1995 Lexus SC300 that I turbo charged.
I'm swapping a 5.0 speed density EFI from an 89 Lincoln Town Car into a 72 convertible Mustang and I can't get the thing to run good. I didn't install the smog stuff and the only codes I'm getting are related to purge solenoid, and EGR. The EGR valve is still installed and I just wired it in today to see if there was any change. Nope.
I have new Motorcraft plugs, wires, cap & rotor. Timing is set at 10 BTDC with the little goodie unplugged. Firing order is correct. I have tried swapping TFI, PCM, and MAP, none of which made any difference. I don't have a fuel pressure gauge, but the inline pump from summit is rated at 45 PSI and lots of fuel squirts out of the schrader valve on the fuel rail.
It runs rough through all the RPM range and has so little power that at full throttle, the engine really doesn't rev up all the way. The engine ran great in the donor car, so I obviously messed something up - I just don't know these motors well enough and I'm hoping you do.
Here's a VID for your viewing pleasure.
