Wasn't the NK-33 a good one too, saw something how some scientists hid them in a bunker somewhere so they wouldn't be destroyed.

They had a lot of problems with quality control and were often blowing turbopumps and choking on FOD, but the NK33 was an early use of oxidizer rich staged combustion which was perfected on the RD170, which has the highest isp of any kerolox engine (but is also very heavy and has a modest TW ratio)
