Converting to mass air on the 5.0

[Gary Lewis]

Yes, seems once he got it sorted out it runs great. Fiveology sells kits but I essentially built my system using almost all stock Ford parts with the exception of the intake system, I had to fabricate an intake system since the factory MAF 460s are only slightly more common then hen's teeth. I started with a 1995 Lincoln Continental MAF as it is almost exactly the same as the 460 one, same physical size and mounting. I used a 5.0/5.8L MAF air filter and modified it to attach the 90 mm MAF to it, I used a pair of 4" expansion hoses for the connection to the wye going into the throttle body. Since the 460 throttle body is (a) larger than the 5.0/5.8L throttle bodies and (b) horizontal and © located roughly over the center of the engine. I had to get from the air filter to the throttle body over the air conditioning compressor. I fabricated an elbow from a piece of PVC pipe elbow and a piece of 4" thin wall conduit, connected the IAC hose and crankcase closure hose to the side of the conduit. I used another length of conduit from the air filter to the air inlet to the engine using the two silicone bellows so the engine motion wouldn't break anything. I updated it to a closer to stock system and finally managed to obtain a factory 460 MAF intake.

One thing very important, ALL air going into the engine must pass through the MAF, even the PCV closure hose has to connect behind it.

I think Big Blue is gonna look just like the factory pic as Mark/Dyn Blin found hen's teeth.
