I think the poor reputation is misplaced, seems to be based on the reliability issues that they worked through from the very early Jensen Healey engines (have read that they agreed to supply them in order to work out any issues, without the car carrying the Lotus badge).
They developed that engine for some considerable time in various forms (couldn’t have been that bad) and even the early engines can be tuned to develop some pretty good power with no real reliability issues - modern machining techniques, improvements in oil tech, gaskets etc all help considerably.
Have an Excel with one in, 2.2 non Nikasil linered with a fully ported/flowed head, rods, pistons, balanced crank, cams and all the usual things done to a built engine - around 210bhp and still nice to drive on the road whilst having a decent increase over original.
You could build a 62 replica but you would lose the use of the gearbox, think that a tube chassis MGB would be pretty interesting. Maybe with bodywork similar to the 1990’s MGRV8 to really make people look twice...?!
Failing that, a retro rally replica - they did fit them into Talbot Sunbeams and Vauxhall Chevettes after all.
