I'm afraid that the "small blocks" that NASCAR runs do not share
one single solitary part or design with any A, B, RB or Hemi engine.
They are a stand-alone powerplant built to the rules (358 max cu. in.)
and are completely unique. They don't even have the same intake and
exhaust port spacing and positioning as any Mopar street motor.
Not even apples and oranges. More like apples and shift knobs!
