I have an 87 f150, I have no idea if it's speed density or maf. Yes I know 89 was first year for maf, the reason I am asking this is because when I got the truck it had tons of mods on it as is. I'll try to post a picture of the setup, but it has two hoses running to the air filter and back. I'm no sure which one this setup would be?

MAF as in mass air flow wasnt until 1994-95

In mustangs they started in 89, 88 in California. I forgot to mention the engine is out of a gt. I'm running a 10:1 compression as of at the moment

My 92 is MAF. And does it have a cold air intake or a turbo on it at all? Because that would explain the extra lines

Two hoses attached to the throttle body? Most likely I would say MAP. All the MAF ones I've seen are one large tube that splits at the TB. Plus the MAF sensor is attached to the tube between the air box and TB.
