Joey, The 312 unblown engines were something slightly under 245hp unless professionally tuned and the compression ratio was put on the 9:5 to achieve the 245 as foctory specs. Using stock specs from 245 HP too 380 HP you can see the HP jump is 135 HP. John Mummert backed that up when he built and dynoed Frank Rices red & black 57 custom 300 which backed up holman moody on the same numbers on a stock 312 when they were building 312s for nascar in the mid 50s. Ford used the low 300 HP numbers purposely to get around insurance cost to the public.

Alan, I noticed you're wanting some ballpark numbers on horsepower from the yblocks. Ford did not tell the truth about the hp #s on the 312s bask in the day. These engines could turn 5000 rpms easy enough if the valve springs were up to snuff stock. A stock 312 supercharged was advertised at 300 hp from ford which was way too low?????? According to the Moody bros and Frank Rice (red & black 57 ford) who had his Stock 312 dynoed and just adding the supercharger it made around 370 to 380 HP and 420+ ft. lbs. stock. And with good valve springs and heads 7000 rpms is not out of reach. A 289 k code mustang can be beat on the bottom end and top end because these engines torque out really well. A supercharger makes more than 20 HP. A good friend of mine Banjo Matthews of nascar fame who passed away some years back told me when he built the 312 too 350 HP, Bill France made him stop because it was legal to bolt on a supercharger and that was pushing if my memory is correct closer to 500 HP and lasting 500 mile races. Much tougher thn chebbes. Hope this gives you a little knowledge on just how GREAT these YBLOCKS were and still are  . So Gary if a supposedly 300hp blown 312 was really making 370 or 380, how much more than 245 do you supposed the unblown 312s were?

Huh, I'm looking for '63 to '64 info, though, both my truck and the junkyard truck are in there.

Never on the 53-56 ford trucks. They did use a 3 spoke style on the custom cab trucks 57-60 , but I think they used a different steering wheel too. I'm not up on the 57-60 stuff. Charlie was correct on the lightning bolt meaning 6 cyl in 65 and 66 If a 53-55 had a 6 cyl the grill had a star instead of the v-8 emblem and on the 56 grill if the truck had a 6 cyl the grill was plain and the v-8 said v-8. But all 53-56's had the hood center emblem with the gear and lightning bolt. Clear as mud!

Do those ever come on horn buttons with the three spokes, instead of just the center piece?
Like the wheel in this picture:

The horn button in the center of the steering wheel on my '58 F600 with 292 has the gear and lightning bolt.

I think, for the '61-'66 series of trucks, '61-64 had the gear and lightning bolt whether it was an I6 or a V8. '65-'66 had the gear and lightning bolt if it was a 6 and a V8 emblem if it was a V8.

Yes, though specifically the gear and lightning (that's the only part on the horn button). I've always thought it meant "Super-Duty", until I learned that was a newer term.

Is this the emblem you are referring to. I always associated it with big job trucks.
