Twin Cam motor rebuild

Some time this Summer we plan to rebuild the motor of the Europa Twin Cam Special that appeared in the garage a month ago. No real issues, but there are at least 57,000 miles there. Not looking for extra power, just as solid as we can do, maybe fancy her up a little bit.
I've been advised to use the cartridge type water pump deal from Dave Bean, and have looked into the twin Weber conversion.

I'm interested to have some suggestions and ideas as to what one might do for stronger internals etc that are reasonable for a street only classic. Again the aim is for reliability and perseverance.

Anyone can make something complicated. It takes genius to make it simple. Einstein.

Cartridge pump is a good idea especially if the car isnt going to be used all the time. For a road car the internals are fine but these days the cheap availability of forged pistons is a big advantage and I'd have a set of them in it for sure. The Strombergs are really underrated and in good condition they make the engine more tractable than Webers. Webers look cute though and there is better general availability of parts and local expertise. Lightweight flywheel is also a nice upgrade. 2008 Exige S PP, 1984 Turbo Esprit, 1979 Esprit JPS #25, 1968 Elan +2
