Can anybody tell me if there is still a Ford Racing mass air conversion kit availible anywhere for the 87 to 93 F150s?? I've got a built 351 in it with a 4 speed. She runs good but I think It'll do better with a conversion on it. I've called all over colorado and cant find one. Fords discontinued it. I'm at the end of the rope, I dunno any other way to convert it. Other than scrounging for parts on old mustangs and ebay. Any suggestions? Thanks!

 

Look for a 95-96 donor truck. Take the harnass from the computer forward, including the computer and all the attached sensors. I am pretty sure 150's and 250's had them, then you can play around with bodies and maf sensors. You can tell mass air by a single hose from the intake unlike a dual hose from speed density. It will probably be allot cheaper than the racing kit.

 

I was looking at a 95 bronco with the mass air it still had the twin air tubes, the air box only had one outlet going to the mass air sensor. After the sensor there was a splitter connecting two hoses to the throttle body.
