I have a ‘93 with a 351 and was wondering what the cheapest way I could go about converting from sd to maf? Maybe go to the local pick n pull? if that’s possible what would I need?

 

Yes, the most economical option is often to source a complete system from a salvage yard—specifically from a Ford Mustang GT or a Ford Crown Victoria equipped with a Ford mass air flow sensor compatible with 5.0/351 engines. You will generally need: the MAF sensor itself, the wiring harness (or pigtail), a MAF-compatible ECU (such as an A9L or A9P), and potentially suitable fuel injectors and a compatible intake tube.
