460hp
It all depends on what year 460.The earlier 460's found in Lincolns from '68-'71 had a 365bhp rating@4,600rpm with 10.5:1 compression. Starting in 1972, Ford cut the compession ratio to 8.0:1(and later upped it to 8.5:1),and started using net horsepower ratings. Generally car 460 engines were rated between 212-220 net horsepower, while 1970's era truck versions were slightly higher. Starting in mid-1987(April 1st approx.) the 460 recevied EFI. The horsepower rating was 230 net@3,600rpm. This was later increased to 245@4,000rpm in '94-'95 engines. Motorhome&Superduty(F-450) chassis trucks had a 255@4,000rpm version of the EFI460.Most 49-state EFI460s have 8.5:1 compression,some California-bound EFI460s had 8.8:1.
Torque rating of early 10.5:1 compression 460s was listed as 500 lb./ft@2,800rpm, while post-'71 engines had about 357-365 lb./ft. rating at 2,400,or 2,600rpm. Later EFI460 truck engines had 390 lb./ft.@2,200rpm,400@2,200rpm,400@2,400rpm,and 405@4,000rpm. The latter version being the 255 net horspower version found in motorhome chassis,stripped chassis,and F-superduty trucks.
