AMC 304's were not used in IH vehicles. The 304 was an IH motor. If you find a red 304, I would assume it was just an emissions model that Frank referred to and the red paint is just a coincidence with respect to IH. IH also didn't make a "400" or a "401" of their own according to BinderBulletin.org. The largest IH-made V8 displaced 392ci and they call it "the 392". However, I agree that they referred to the AMC 401 as a "400". See below for some search results from BB. You'll have to scroll through some of it due to some random search hits. http://www.binderbulletin.org/forums/faq.php?s=&do=search&q=AMC+232+258+304+401&match=any&titlesonly=0 Try different search combinations including the keyword "AMC". It coughs up some bits of info regarding special tools to service AMC drivetrains and transmissions in the IH world. -Spro -------------- Original message ---------------------- From: Frank Swygert <farna@xxxxxxx> > John, you got that backwards!
