Yall, forgive my ignorance but I am fairly new to Ford trucks.

I want to know how much horsepower a stock is put out by 1986 460 motor and Holley 750cfm carb on top. BTW, it has about 26,000 miles on it and seems to be in good shape as far as I can tell. Any clue to the torque rating?

Thanks yall.

 

Probably about 224 HP....... but with lots of torque.

 

Thanks man. So 224HP is all it puts out, I would have figured it would have been quite a bit higher. Doesn't the 351 put out at least 250HP? Any idea what the torque rating would be on the 460?

 

For 1986, the ratings were, 245 HP @ 3800 RPM, and 385 ft/lb @ 2600

 

You can increase that HP by a significant amount by a simple timing gear change. Put in a set of gears for a pre-1972 engine (which are not timing retarded) and there will be a big difference.

 

Whoops,..... My 224 was supposed to be 242 HP.

I'm glad someone corrected me.

Thanks

 

OK, so replacing the timing gears(Same function as a timing chain?) with the pre 72 ones from a 460 it will give a big boost to the HP. I imagine this isn't the easiest thing to do, is it? Would it probably hurt or help the fuel efficiency? Also, would this probably be a junkyard part or better to buy new? Any other drawbacks to doing this? Thank you all very much for your help.

 

ok, I know it's an 88 engine in a 79 Bronco, but I pulled a 185 hp and 270 lb/ft of torque out of a stock EFI 460, a general figure puts it at 260 Hp and 360 lb/ft of torque

I still think that the Tq # is out a bit, a little on the low side

 

hey, i'm about to put a 460 in my 89, but before i do i want to do some mods to get it up to about 450 hp and tourque. i'm thinking 3 angle valve job on the heads, demon 750 carb, a cam and headers. any other ideas. please let me know.

 

A 1984 E-350 Van with a 460 and auto makes at the rear wheels 214HP and 382 lbs. ft. tourque. I do not remember what rpm that was at. I hope this helps you.

 

I wouldn't use a junkyard timing set myself.

Yes, you have to remove the integral front cover and the crankshaft pulley. Both can be a b*tch if they haven't been off in a long time. It's not uncommon for the water pump bolts to shear or strip, as the front cover is aluminum.

Putting in the pre-'72 set restores the engine to pre-smog cam timing.

Another easy way to boost the HP is to install '68 - '71 high compression heads.

So far, this is all bolt on. You can also change the cam fairly easily if the heads and front cover are off.

 

Alrighty then, I thought it was going to be something pretty involved to replace that stuff. I'll be taking a few automechanics classes in school and this might just be a good project for me to do with a good instructor around to make sure I don't really screw this otherwise good truck. I imagine it would be best to replace the heads, timing gears, and cam at the same time right?

It just amazes me that Ford would produce a 460ci engine that only gets 245HP and puts it in a truck that together get 10mpg on the highway from the factory.(The 92 C-1500 with 350 I drove before put out that much HP!)

So aproxamatly what was the HP output of the pre-72 460's?

Thanks again.

 

My 1969 Chilton's shows that a '68-69 460 made 365 HP and 500 ft/lbs of torque. This was measured at the flywheel with no accessories on the engine.

In 1972 (the same year that smog really kicked in, with retarded cam timing and lower compression) they also began using a different method of measuring HP that made the numbers really fall.

 

Where are the directions for this mod - installing pre-72 timing in a 460?

Mine is a 78, looks like the engine is out of a Lincoln of the same year.

 

I would like to know about rough h.p. and torque specs for a '73 F-250 w/ 460.
