Hello, I am trying to find out what the stock Hp and torque are for a 460 late 70's model. 2bl &4bl. Thanks

 

My 1978 Mercury Marquis has a 460 4bbl.

Stock with single exhaust it had a whopping 197 hp. I think I recall 358 ft-lbs, but I'm not as sure on that one.

My engine is an "A" in the VIN code.

With dual exhaust they jumped to about 220 hp.

I think the Police Interceptors, which had a different VIN code, had duals & a hotter cam and were around 240 hp.

But, take a late '70s 460, put duals on it, scrap the cats, and give it an Edelbrock Performer carb/intake combo and you'd have a nice animal.

Oh, I don't think passenger cars ever had a 460 2 bbl. 429 2 bbl maybe. Not sure about trucks... mines a 460 efi!

 

I do belive my stock 460 in my 77 f150 was 240 hp stock.

 

I guess my 1969 Lincoln 460 with factory rated 365 hp and 500 ftlbs torque is worth freshening up and dropping into my 82 F150 stepside!

 

Well, '69 was a great year for the 460, but the 365 was SAE gross hp. All the other numbers are SAE net hp, which is thought to be a more consistent scale, but always gave lower numbers than the old gross formula.

I think it's still worth dropping into the stepside, but I'd say that about any 460!

 

Ya, i grew up driving in 1971 and noticed the ratings change in 72. This particular 460 is the only one to come from the factory with 10.5:1 compression. I now have a modded 400 in it, BUT, man that 460 was unreal in factory form!

 

Oh, by the way, my tranny will bolt right up also!
