there will be the mass airflow meter right after the air filter box on the engine side if your truck is MAF, it is unmistakeable. Speed density has no such meter.

my 95 302 is not mass air.

Really considering this option too, because it has really sluggish throttle responce.

All F150's were mass air in 96 with OBD-II. A few 94's and 95's had mass air but I would say the majority were still speed density up until 96 (the F250's and heavier trucks remained speed density, with very few exceptions until the super duty came out in late 98).

I have a 95 F150 5.8L 351 V8 (XLT) which has speed density
my brother has a 95 F150 5.8L 351 V8 (XLT Eddie Bauer) which has a mass air flow sensor. 95 was the transition year for V8s.

It wasn't really a transition. The 94 and 95 trucks that happened to be mass air were equipped with an OBD-I EEC-IV computer, while the 96 F150's used OBD-II compliant EEC-V computers. Maybe some of the fuel and timing maps could be carried over, but the computers themselves are totally different animals.
