I had to look for this one as I wasn't sure if I was remembering it correctly as a Knafel car...but it is/was!.
Much like one of Smokey Yunick's accomplishments, perhaps one of the greatest racing rule bending was Knafel using the Canadian Pontiacs having factory Chevy engines thing to legally run this probable L72 Acadian!.

Info/Pic below lifted from a previous thread here;
<span style="font-style: italic">...The Knafel Acadian ran in the NASCAR Ultra/Stock drag racing class where the rules stated that the car and engine had to be of the same make. Knafel decided to go with the Canadian Acadian so they could run a very competitive 427 engine and still be considered a Pontiac. Because the Acadian used a Chevy drivetrain, this was considered legal by NASCAR. I don't believe NHRA ever did recognize any of the Canadian Pontiacs. The photo below is from a 1967 points meet at Suffolk Raceway and the Chevy wagon in the far lane is Ted Hartman's "Bad Banana"...</span>
