Stock 360 power?

From the many-times unreliable Wiki:
215 HP at 4200, 375 tq at 3600 for 1968. These would be the old gross HP numbers, so slice as much as 20% off for the SAE Net HP calculation adopted in '71 or'72 or so, and I saw a quote of 196 HP for those, not the full 20% loss.

20% off 375 makes it 300. I was thinking, even with 20% off, that's still a lot of torque... until I did the math, lol. My little 302 is rated 275 ft-lbs @ 2400 RPM. I've rode in a 390 powered Ford, and it seemed to run really good. I know the 360/390 are brothers, and I expected better numbers than that. I wonder what they'd put on a dyno, since it's hard to know the real horsepower/torque numbers with the different standards and different times.

While the 360 and 390 are identical in almost all ways, the 360 suffers from lower compression and a below deck piston height, both proven power killers.
IIRC, the net torque number was something like 336, but I'd have to search for hours to confirm.....
The 360 does not seem to have suffered the full "20%" loss, due in part to the fact that it was already low compression and probably had a smog pump and some other early smog stuff from day one, having been a '68 intro model. The numbers drop was mostly due to the gross-to-net change, but additional smog efforts contributed as well.

Because it is so easy and cheap to make more hp by installing a 3.78 stroke crank, 390 rods and higher compression pistons, and make it into a 390, that is what most people do. If you were a die hard 360 fan, all you would need to do is buy aftermarket high compression pistons, aftermarket stronger rods, better flow heads, intake, cam etc. and you would have a potent 360. It would put the hp close to the 390 but for much more money.

Interesting about the compression being so much lower on the 360 than the 390, I wouldn't have guessed that, but I don't have a ton of experience with these engines, either. I do know that I enjoyed my ride in the stock 390 Ford truck I rode in. Sure, it was a good running truck, but that thing seemed to have some good pep for its age. Really good pep.
I had a friend back in high school that had an old Ford with the 360 in it. He seemed to like it. Never heard him say anything bad about it, reliability or power-wise.

The other problem with the 360 was the 1972 and later years had different cam timing making power even lower.

Fix both problems at once with that scheme. :)
(if there are any that'll fit, no matter what brand)
I haven't give up on the idea of a 390 or 410 I'm still looking for a 390 or
390 crank and rods, just not having any luck. :/
I've sure enough disappointed a bunch of guys around the area tho with
my 1/4" dowel. They weren't lyin' about their 360's being 390's, that's
what they were told and I'm beginning to think it started way back with
the dealership's sales staff. :/

After getting my 252/252 Comp "Economy" cam (set straight up)
I can feel the power band back off a little at the upper end and can't
seem to find the low end limit to the power band. Before, the sucker
couldn't pull from 31 miles an hour in forth gear and could feel no
dropping off at the upper end. Now I'm afraid to try too hard to find
the low end in 4th gear but 12 miles and hour is no sweat. :)

My brand new '75 F150 360FE T18 came with only an EGR, PCV, lean
low speed circuit, lean idle mixture (factory set with mixture screw caps)
and the retarded cam timing ...as smog stuff.
...and couldn't pull itself from a level spot without putting it in 1st gear. :/
Believe it?
The clutch being crappy didn't help anything either. :/
(suspecting the bell housing is not straight!)
Defeating the EGR helped a bunch (did that the first few months but
couldn't be seen from the outside) but the only thing to really "fix" it
was the 252/252 Comp "Economy" cam with its "tractor like" tall
but short duration lift and its built in more advanced timing.

ps- No pump or charcoal canister came on it.
