    Since I have looked for these figures in the past I thought I would post them up so the next person who is curious can see them. These figures are from the CTS-2304 manual that covers the 1972-75 Scout II models.

    4-152
    Brake H.P. (Max) @ RPM 86.9 @ 4400
    Brake H.P. (Net) @ RPM 80 @ 4400
    Torque (Max) Lb. Ft. @ RPM 135 @ 2400
    Torque (Net) Lb. Ft. @ RPM 129.8 @ 2400

    4-196/4-196E
    Brake H.P. (Max) @ RPM 110.8 @ 4000
    Brake H.P. (Net) @ RPM 102.7 @ 4000
    Torque (Max) Lb. Ft. @ RPM 181 @ 2000
    Torque (Net) Lb. Ft. @ RPM 176.1 @ 2000

    6-232
    Brake H.P. (Max) @ RPM 145 @ 4300
    Brake H.P. (Net) @ RPM 120 @ 4000
    Torque (Max) Lb. Ft. @ RPM 215 @ 1600
    Torque (Net) Lb. Ft. @ RPM 202.5 @ 1000

    6-258
    Brake H.P. (Max) @ RPM 140 @ 3800
    Brake H.P. (Net) @ RPM 122.3 @ 4000
    Torque (Max) Lb. Ft. @ RPM 235 @ 1200
    Torque (Net) Lb. Ft. @ RPM 204.1 @ 2000

    V-304A
    Brake H.P. (Max) @ RPM 193.1 @ 4400
    Brake H.P. (Net) @ RPM 180 @ 4400
    Torque (Max) Lb. Ft. @ RPM 272.5 @ 2800
    Torque (Net) Lb. Ft. @ RPM 262 @ 2400-2600

    V-304
    Brake H.P. (Max) @ RPM 193.1 @ 4400
    Brake H.P. (Net) @ RPM 180 @ 4400
    Torque (Max) Lb. Ft. @ RPM 272.5 @ 2800
    Torque (Net) Lb. Ft. @ RPM 262 @ 2400-2600

    V-345
    Brake H.P. (Max) @ RPM 196.7 @ 4000
    Brake H.P. (Net) @ RPM 168 @ 3800 (Yes I know this seems like it should be wrong, but it's not)
    Torque (Max) Lb. Ft. @ RPM 309 @ 2200-2400
    Torque (Net) Lb. Ft. @ RPM 288 @ 2000

    V-392
    Brake H.P. (Max) @ RPM 235.6 @ 4000
    Brake H.P. (Net) @ RPM 191 @ 3600
    Torque (Max) Lb. Ft. @ RPM 356.5 @ 2800
    Torque (Net) Lb. Ft. @ RPM 307 @ 2400

    Hopefully this will help everyone who is wondering what horsepower and torque their respective engines have and how they compare to other non-IH motors.

    I know people turn their noses up at the AMC 232/258 series, but one cannot argue with how early the max torque comes in, which is ideal for a 4x4 crawler. Score one for the Jeepers.

    The 196 is also a low-down torquer at 2,000 rpm. I had one of these in an early and it made for good creeping....

    No doubt in my mind that the 258 I6 is one of the best all around small truck engines of all time. I wouldn't want it anything much larger than my CJ5 though, or an early Scout. I would hate to have one of the FSJ's with the 258...I imagine that would not be a good freeway flyer.

    304A... is that the AMC engine? I have a 71 1110 pickup, with the IH engine, and wonder if those numbers are the same?

    woah. old thread dig up here. no no and no. a quick search will show that the AMC 304 and IH 304 share nothing....nothing in common. amc 304 was never installed in an IH vehicle. 304A denotes later emissions engine i think. cant remember, but if i hit the search button it will show me like a glorious light

    My 304 needs to be completely rebuilt. And I'm pulling out but there is a guy selling a 196 real cheap and I'm thinking of putting it in my 74 scout II.

    Is that a bad idea or will it even work?

    My engine has been shot since I bought my scout and its never been on the road since I've had it so I won't notice the difference in horse power. But does it even have enough to power a scout II down the road?

    Thanks guys

    Well, 110 hp vs 193 hp. Even a tired 304 will out pull a 1964 banger. You could order a new Scout II with the 196 so it works albeit slowly. Use 304s are not that rare, even in NC. Check the truck salvage yards. You might score a 345.

    Look for and send a PM to GMBARKER on this board. He's in Ferguson, NC and should have several engines available. I'm not sure where Ferguson is, but it's in state at least. Sounds like a ROAD TRIP!!!!!!

    I think its about 750lbs. or 340kg. Probably a little more with all the accessories still bolted on.
