460cid stock HP rating & torque specs
Hello. Have a simple request. I've just installed a 460 intop my `72. I've looked in all my manauls for horse power rating and it says N/A. specs on all the other engines but the 460. Does anybody know what the HP & torque specs are for a stock 1978 460 non-catalyst. Just curious. Thankx

that works for me bro! the 460 cant be that weak, those numbers gotta be wrong, a mustang 302 motor with gt40 heads would smoke a 460 otherwise and they dont

It all depends on what you are doing. A 460 will pull well due to torgue. What did you expect to see? A large displacement engine during the smog days. Hp does not play near as much a factor until you get into going fast. Kinda makes ya wonder what just 300hp would feel like doesn't it? I don't think almost 1 ftlb of torque per ci is all that bad considering we are talking about the heavily detuned days of the 70's. I take it you aren't old enough to remember those times. We went from 350 - 450hp to 150-250hp overnight and stayed there for at least a decade.

I know what 300hp feels like, better yet I know what 330ft lbs feels like from a lt1 350 that my 94 z28 has..its not stock, stock is rated 285hp 325-330ftlbs depending on who you ask and it makes that torque at 2000 rpm.
Im 35 so i heard it all growing up from my dad. the 80s cars were really bad as well. i just thought a 460 would make 400ftlbs or more, rotating mass and all.

Generally speaking a well built engine matches hp & torque. Hp to weight ratio has plenty to do with going fast. There are other factors that change outcome as well. If hp didn't matter top fuel cars wouldn't be working so hard at getting more of it.
The point being of age was you didn't live through it. You didn't start driving until it was over. The years of beginning onboard computers, smog pumps, ultra low compression, fuel supply altered intentionally to harm earlier engines in order to get rid of older vehicles. Lady Bird Johson started it all and you still see it today. Obama's "Cash for Clunkers. Hearing about it and living it are two entirely different things.
The 460 was born at the beginning of the heavily detuned time in history. With all the restrictions put on auto manufacturers I personally believe it was built part to be "bigger" than the Chevrolet 454 & part to get more power from heavily restricted engines. After all nothing beats cubic inches!
I often wonder what we would have from both the 460 & the 454 had they started life like the Hemi.
