Have Motor Home set on 1977 Ford Econoline 460 cu. in. Whats the HP?
As an early smog engine, my guess is not many. For full specifications try google, should direct you to sources showing both the HP and torque curves.
Found this is about 10 seconds on Google;
1976 460 started life with:
HP: 230 @ 4000 rpm
Torque: 359 ftlb @ 2600 rpm
Should be close.
