IH made a lot of piston types back then no longer made. After that I think IH just started using fire crater pistons for replacements. At one time you could get them for higher altitude, + more compression. High altitude and some LP pistons in the 400 and 450 era were step head design to raise the compression. 400 came with 4 inch bore sleeves and not long after they were selling the 4.125 bore kits for them. If the person installed say a 8000 foot piston or other combination that would raise the HP. At one time lots of different piston and sleeve sets were sold for C-264 and C281 engines. Not counting distillate and kerosene or SM and SMTA engines. 400 used 2 different cylinder heads for LP, early and late, late also used on C-281. 2 different piston pin sizes. Early LP head was the same casting as a gasoline used on 400 and 450. IH tests on a 400 engine equipped with fire crater pistons obtained right around 60 HP corrected to sea level. That engine was tuned to go out work continuously. Use of higher octane fuel and tuning on a dino could result in a 60 HP reading depending on what else is done to the engine. Depend on who interprets the dino readings also.
