Where did this term "chunk" come from?

I know a guy who pronounces it Elderbrock. :BangHead: Every time I hear him say it, I ask if it's an OLD intake. Been asking him 20 years....and he has yet to figure out why I ask! :realcrazy:

And just think of poor Weiand- they had to put the pronunciation right on their manifolds because nobody could get it right...
