87-88 Non california models did not come with a mass airflow metering style system. They are referred to using a speed density method of measurement. All 89+ Mustangs all had mass air flow meters.

i see, just a quick question, i might have to make another post.. but do you (or anyone else) know what size throttle body came on stock 5.0 HO motors (more specifically my 88 LX)????

these questions are leading to a massive intake upgrade. most like a bbk ssi-series manifold and a chicane fox box cold air intake kit...

58mm throttle body

How many times have we beaten each other to that answer.

If you are going to do this intake upgrade i also suggest to convert your car to MAF insted of your speed density system. It drastically improves driveability, at least it did in my situation. I would also suggest doing this before you buy your cold air intake, it'll save you the trouble of having to buy a new one if you do decide to convert to mass air later. If you have any questions on how to convert to MAF i will be happy to answer them.
