The 94-98's were the slower mustangs. The 94&95 had a 215hp 5.0 and the 96-97 had a 215hp 4.6 and the 98 had a 225 hp 4.6. The 99+GT's all have had a 260hp 4.6 stock.
The mach 1's still have the 4.6, which is 281 cubic inches, but they come with the 4v heads and the aluminum block(GT's get the 2v alum. head and iron block, while cobras had a 4v alum. head and alum. block). They put out 305hp stock.
96-98 cobras put out 305hp stock, while 99,01 cobras made 320hp. The new 03 and 04 cobras are making 390hp
