Yep, making money VS. making horsepower, can't debate that one.
Business vs. "Passion".

By now everyone knows a small block mopar can run it's @$$ off.
Often times harder than most anything else comparable.

But, try selling parts for them + comparable parts for other Mopar engines for 20+ years or so. I found out real quick, Big block parts far outsell small block parts. Doesn't matter what the commodity is. Even Gen 2 426 hemi parts outsell small block. At one time i believed it might change over time....but the market has shown me it has not.
