i was told that an 89 5.0 has 10 less hp than a 1991 5.0 but the engines are exactly the same as far as i can see. what makes the difference.

thats b u l l s h i t. from 1987-1992 all 5.0 mustangs were rated at 225 hp. in 1993 they changed from forged to hyperpuetic pistons and the rating for horspower dropped to 205, but this is said to be mainly from Ford changing how they measure HP. the only real difference under the hood in any of these is that in 1987 and 1988 the 5.0 was controlled by a speed density type computer. these cars lacked a mass air meter and were said to have run harder than the mass air versions(1989-1993), however i have drove both and i really can't tell a difference. however it is much easier to hot rod the mass air units.

There is NO difference. Both years were 5.0 literes and 302 C.I rated at 225 HP. Who ever told you that doesn't know what he or she is talking about. From 1986 to 1995 they stuck the 5.0 302 in the Mustangs. From 1996-2004 they stuck in the 4.6, which is, I think 200 C.I.

It comes down to who tested it. and how they tested.
Also their could have been design improvements to the airflow intake or the exhaust. the cylnder heads also can be ported.
