If you like Russian R7 derivatives, there are some configs of the RD-107/108 with ridiculously high reliability. https://github.com/KSP-RO/RealismOverhaul/blob/master/GameData/RealismOverhaul/Engine_Configs/RD108_RD118_Config.cfg e.g. there's one variant, RD-108-8D727 and the RD-107 equivalent, that in real life had 1400 successful flights and no failures, so it has lots of 9s in its reliability scores.
