Sounds like: Why is an orange orange named an orange.....? By the way: Which came first - orange the color or orange the fruit? Orange the fruit came first. The word came into English either from Old French 'pomme d'orenge', or from the Spanish 'naranja'.
I thought it was called "Hemi Killer" because this the cam grind (241/241) is what was specifically made and used in the Buick Stage 1 for one of the Hemi vs Stage 1 shootouts many, many years ago. Maybe it was the shootout with the yellow GSX that raced the Hemi Cuda. the Buick beat the Hemi so bad in the first round that the Hemi refused to do a second run. The Buick won and therefore the name was given to the camshaft. I think the GSCA sold them initially back in the days when they sold cams, now T/A picked up the slack and offers it after the GSCA stopped. Isn't this correct? btw, I have one of the old original Hemi Killer cams from the GSCA and it ran really good in my all-iron stock appearing Buick big block (12.1 @ 111). But it doesn't sounds stock so it doesn't really fool anyone.
Thanks, I thought it might have been from the hemi ,stage 1 race. All this talk makes me want a glass of orange juice !
