i have 1989 f250 with a farly new 460 i was wondering what the average stock horse power of a 460 is. the truck has true duals that come out behind the doors with flow masters. dual cold air intakes and almost everything is aluminum stock. it has alot of power and torqe but what is average?????

 

It seems to vary from repair manual to repair manual. Around 220-240 HP 390-410 torque. But that is a ballpark figure.
