Are 340’s rare

Dart always beats the Camaro off the line but by 80 mph the 396 passes and walks away from the over square 408 Dart.The 396 with 3.75 stroke just flat out revs quicker.

This is what I would expect.
340 rare? Don't know I've never looked for one.
I'll take a bigger bore engine every time.
