Approximately 100 Cobras were produced with the 428 P.I. engine, starting with CSX 3201 and ending with CSX 3301, with a few stragglers, CSX 3305 and 3306. I count only 11 of those as having their 428 engines still in place, according to the the 1997 registry.
The two original Shelby brochures I have list the 427 as 425 hp, 480 torque and the 428 at 355 hp 420 torque. The document shown above listing 390 hp from Shelby is fascinating. I haven't seen that one before.
My 428 powered Cobra is plenty fast for me!
