hey yall im building my 68 mustang and picked up a 5.0 with harness and computer that was in a fox, the only thing is its speed density, does this mean it wasnt originally from a fox? also how could i go about converting this to mass air, also anyone have any tips on installing the efi 5.0? ive already read the articles in the faq just seeing if anyone has any more tips

Swapping SD over to Mass Air is pretty simple. Primarily changing the EEC and adding the MAS sensor and wiring to the intake. There are lots of sites out there explaining how the pre 89 Foxes can be updated to MA.

The question is, why do you want to convert to MAF? SD works fine when tuned right. There's a reason all the powerful aftermarket EFI race systems are SD. And with a system that runs in alpha-n at low rpm you can idle anything.
