Thread: Street&Performance EFI harness and computer for Ford 5.0

Tweet

I have a new never used street& performance EFi harness and computer for a 1987 up 5.0 ford.I also have a upper and lower in that has been polished for a 1987 up 5.0 ford.I have had this stuff for a few years and never got around to putting it in my car and now i sold the car and don't need it anymore.I will take 300. for harness and computer and 150 for the intake.

I have sent you a personal message (PM)

Thanks for letting me know it is a speed density setup. I called street and performance and they said there is no realistic way to change it for mass air. I guess I will pass on this. Best of luck on your sale.

Still got it?

yes i still have it
