Hi There

I've just been through a similar exercise and to add to the comments on the rear rope seal, It can't be retro fitted with a later type of seal. The rear of the block is different with a bolt on seal housing. Also the seal runs in the flywheel flange which will need to be reground if using the original crank. The advise i received was to go for a later block and transfer all my internals over. The later blocks have the later type lip seal, holes cast in the crank case webs for better breathing, Different crank case breather, eliminating the need for the 'bean can oil trap/Filler, and improved oil pick up pipe/strainer.

This is all probably an over simplification and the choices seem endless. such as do you go for the 2.2 crank and high compression pistons.

I was lucky and dropped on a new set of standard Lotus pistons and liners for £100 ($150) and i got a Lotus (Esprit i think) short engine off e bay for £25 ($37)

Not up and running as yet as cars not ready.
