Beautiful truck there, doesn't look like a spec of rust is on it. Feel free to message if you need any help

 

Thanks fella and deff will do y'all have been a ton of help and yea it's flawless I've owned it for 5 years been slowly putting it together the way I want just got a cowl hood for it and a deff set of tires

 

The 5.0 Computer will not really run the 5.8 Lightning engine well. The 5.8 SVT engine is 240HP, the 5.0 is 195 HP. The 5.8 will require over 20% more fuel than the 5.0, and the 5.0 computer will not know that.

The oxygen sensor will compensate somewhat, but it will never be "right". You cannot use the SVT computer, as the 4R70W and E4OD are use incompatible control schemes.

The only exception to this, would be if your 5.0 truck is a mass-air truck, in which case, it will likely run decent (but not perfect)

 

Could I have the computer tuned for the 5.8?

 

Also can anyone tell me how to know if my trucks a maf for sure my truck has wat looks like a maf sensor just want to know if there's a for sure way to tell

 

If your truck has an aluminum chunk near the airbox with a plastic Y pipe between it and the throttlebodys you have MAF and that is a hugh bonus for this swap, the motor will actually run half decent once you give it a chance to adapt.

The flexplate you need is for the 351/AOD combo from a mid '80s crown vic, the 4R70w was never installed behind a 5.8 so any late model 5.8 flexplate you buy will be for the E4OD which has the wrong offset for the AOD and 4R70w.

 

Ok great my truck has that far as the maf goes and yea the link that was posted on here had your convo wit the part number for the flexplate I needed and so since my truck is maf how could I go about getting the a good tune to make the truck perform to it fullest because this is the final step in my truck I've already regeared it to 4:10 which help a hell of a lot wit my 35s I've got some bolt ons for the 5.8 just wanna get it's best if I can
