If you see a 340, 383 or 440 Magnum 1970/1971 'Cuda or Challenger with a Shaker Hood and the Bubble looks too low there's a reason for that. Because all three engines have different deck heights each engine has it's own unique base plate that takes into account the engine's deck height so the Bubble will be positioned properly. Put a 383 base plate on a 340 like this convertible - it's too low.



Here is another 1971 340 Challenger Convertible with a factory Shaker Hood with the correct 340 base plate. Compare it to the one above.
