I have a '94 F-250 with a factory 460. It is mostly stock, except for the K+N filter. What I would like to know is what kind of power am I getting from it(numbers). Is there anyone that knows or knows a website that might have the info I need?

 

I also have a '94 F-250 with the EFI460.From the factory,the 460 was rated at 245net horsepower at 4,000rpm.You didn't say which K&N you have. Is it the flat tpye that fits inside the factory airbox,or the open element type which replaces the factory setup? The flat type should give you about 3-5 extra horsepower. A open element K&N air filter should give an extra 10-15. I've tried both.To get the most from you K&N I'd suggest opening up your exhaust with either a larger diameter single pipe, or 2 1/4",or 2 1/2" true duals.Don't go any larger than that with a stock EFI460. I have 3" duals on my truck,but I've upgaded the 460 a lot,too. Good luck,your truck sounds cool!

 

Someone said my name? Happy April Fools Day!
