Its been a very thoughtful, quite in depth and informative discussion. The basic question I would ask, if you are looking to increase the power of your car's engine performance at some not inconsiderable cost, with a chance of variable results, if there was a more powerful engined car in the range, why not buy that car instead?
I appreciate the technical challenge might be all absorbing to some, but it does seem a much easier more reliable solution when eg a 3.7 Roadster produces 280bhp with the 3 litre producing between 200 and 240bhp for not that much larger a purchase price outlay. Especially when all classic Morgans share the common problem of putting the power to the ground, that will have to be overcome no matter what model you own and the often variable qualities of the gearboxes are shared across several engines. I fully understand the difficulties that obsolesce, lack of spares supply may lead to replacement ECU's , PCB's etc
As they say each to their own.
