Buying a 454 out of a 79 Suburban with Low miles, any clue on horsepower?
Just curious on HP and TQ this engine may make stock. Trying to get a good baseline. Any idea where I can find this info?
Thanks guys! |

factory service manual or manuals like motors or chiltons will give you an idea
my best guess would be around 230hp and maybe 350torque

i looked for it too, i'm surprised it made that in the height of smog and low compression. should be fairly easy to bump that up though.

My book says (old 1979 MOTOR'S manual) 210 HP and 340 TQ. This pic says the same thing. Cdowns is was closer than you thought!
