360 and 390 Horsepower and torque?
 

I can't seem to find many specs on them, I am just wondering what the Horsepower and torque is on the 360/390 for 1967-72 ford trucks...

Anyone know?

Thanks!

Low 200s for HP, high 300s for torque. Truck numbers are lower than the car numbers given here, but just a bit below the 265 hp the list for the 2bbl 390, which was 9.5 CR in a car. When HP went from "gross" to "SAE net" in '71, the numbers dropped. Smog changes didn't help, so expect a later 360 to barely hit 200 hp.

Ford FE engine - Wikipedia, the free encyclopedia

Yea, I know it's wiki, but it mostly right, and close enough.

Ford says for their pickup motors before 1972's kill the horsepower move.

360
215hp @ 4400 and 327 ft/lbs @ 2400

390
255hp @ 4400 and 376 ft/lbs @ 2600

In 1972 360/390 HP was more like 170/185 for trucks :-wink

Cams were retarded 6 deg


All 360/390 truck engines for 1972 and up were .104 in the hole with NO compression

1952

It was only 4° and there is debate as to whether the 390 was retarded at all. As to the compression issue The 60's truck engines only had 8.4 and 8.6 for the 360 and 390 respectively, which was down from the car engine's 9.4 to 10.6.

Well I have degreed 3... 72 and later 390 engines cams..6 deg retarded total ... each of them 4 deg at the chain and 2 deg at the camshaft.

Ford also put the Piston .104 in the hole which gave a realistic compression of 7.5-7.8 depending on the head CC

The degree wheel never lies..and Ford specs Did :-X19

Not arguing with you..just dont trust Ford..

If anyone really doubts this they are more than welcome to break out a degree wheel and find out the truth.......:-X01

It is a Shame that Ford did not do Better for all the Ford Followers they had..or still have....Myself included

The later model 390/360 engines were Just plain lazy

1952

Well then you did it wrong because the factory only used 4°.

Wouldnt the 360 pistons be lower in the hole than the 390? They wouldn't both be .104in the hole. Isnt that one of the main reasons the 360 was a dog was because of lack of quench. Help me out here Bear.

agreed on the 4*, not sure how you're getting 6*. The conclusion we reached about the 390 was that it wasn't retarded at all being that the same part # is listed for pre and post 72 390s, or all other fe's for that matter excluding 360. The 360 is the only one that had a different part # for the timing set post 72.


Also Bear, how do you type the degree symbol?

Different length rods is why the same pistons work in both the 360 and 390.

I shouldn't let the secret out but to get a degree symbol you press and hold the "Alt" key and then press "0" (zero), 1, 7 and 6.

°°°°°°!! HA!! You dont know how long i've been using asterisks. lol

Maybe I should reword my question. Does a 360s piston sit in the hole the same amount as a 390s piston does? In other words is there the same quench on a 360 as a 390? or is this dependant on wether or not the 390 is from a car?

The stroke on the 390 is 3.785". The rod is 6.488" center to center.

The stroke on the 360 is 3.500". This rod is 6.540" center to center.

You do the math.

Yeah that doesnt really help. I found it in another thread though.

For anyone else that was wondering, 60s 390's pistons weren't down as far in the hole but they changed in 70s to using surplus 410 pistons then later recast them as the 390 truck. This brought it down to the same level as the 360.

How can you make a 360 into a 390?

change the rotating assembly.

Install a 390 crank and rods.
