A: I don't know about here in the US, but in Canada there were thousands of IHC pickups with the venerable AMC 6 in them. I had a '75 and an "'80" shortbox stepside with 5 speed, 1 ton axles and 4x4. (It was used to haul 5th wheel prior to my buying it. The rear axle was broken and the owner was told zero available so I got it cheap, swapped in a Ford axle and did nothing else but add power steering. VERY sweet truck!) I don't think IHC used any other AMC motors than the "400" and 258. From: JOE FULTON <piper_pa20@xxxxxxxxxxx> Subject: Re: AMC's in IH trucks....?? To: mail@xxxxxxxxxxxx I'm not an expert but I have looked under a lot of junkyard hoods the last few years. AMC 258 was used in Scouts (and maybe pickups, but I doubt it) in the 70s and early 80s. AMC 401 was used in anything BUT Scouts in the 70s. The IHC engines are much more common (304, 345 and 392) as you would expect. IH V8s all have the word "international" stamped into their valve covers. If the valve covers are missing, I think the IH distributor is located on the back of the engine. At any rate it is not canted to one side in the front like the AMC engine.
