I can give you guys a rough cost estimate for what I spent, so you can decide if such an undertaking is worth doing.


Parts I reused:
Fuel rail. I modified it to fit the Boss 302 intake
Oil pan. Direct fit on the navigator motor
Power steering pump reservoir and bracket. Pretty much direct fit.
Radiator.
A/C Compressor. I haven't charged up the A/C yet, but that's coming.
Fuel Injectors.
MAF Sensor.




Parts I purchased:
04 Lincoln Navigator 5.4 4v (84k miles)- $1600+tax (complete with coils)
2011+ Mustang Boss 302 intake - $500
96-98 Mustang Cobra coolant crossover tube & plug - $70
O-rings for 96-98 Mustang Cobra coolant crossover (2) (they might be listed under a 97 lincoln mark viii) - $10
96-98 Mustang Cobra thermostat housing and radiator hoses - $90
Airaid U-Build-It Cold Air Intake - $300
Airaid MAF sensor housing (hitachi style) - $50
04 Lincoln Navigator alternator - $65
2011+ Mustang GT throttle body - $165
5.4 4v to Boss 302 intake adaptor plates - $220
96-98 mustang cobra alternator bracket - $30
SCT Xcal3 - $250
SCT PRP -$300

Parts I modified:
Transmission dipstick tube - I cut the bracket off, it wouldn't fit otherwise
Fuel rail - I cut the braided line off and used high pressure fuel hose
Heads - To fit the intake, I had to grind some material off on the valley side of the heads.
Alternator bracket - One side fits fine, the other has to be modified because it is too short for the wider 5.4.
Wiring harness - I had to rerun the wires for the drive by wire throttle body and lengthen the wires for the coils.


I'm not saying this is a complete list or the prices are 100% accurate, but from memory this is pretty complete.


If anyone has any questions, let me know. This motor is a TIGHT squeeze in these trucks.

I use the pro racer software. I bought it from Don lasota and he's been excellent with support after purchase. He's very knowledgeable of tuning.

I'm not sure if that intake is great for torque but i know that a good set of cams will help a lot. I'm not knowledgeable enough to make a suggestion on cam specs though

Any suggestions on this. The one thing I change was the transmission from a 4r75e to a 4r100 which I wouldn't think it matters.
