Largest Issue with Rocket engines In KSP are very heavy engines compared to their IRL counterparts with similar size and thrust, this made engines like 48-7S feels OP.

Mainsails had largest TWR in game (can lift 25 more than own weight), but it's quite small number compared to old Saturn I H-1 engine, with size and ISP between mainsail and skipper, 900kN of thrust and weigh of "only" 1000 kilograms (4x less than skipper), which gave him TWR around 100...

From other hand after balancing engines, fuel tanks will require their dry mass and fuel density (bit less fuel units, more dry mass) rebalanced to made it feel right too.
