The 2 litre engine was the most reliable engine we ever had. It was so
good and the crank very very strong as it had lots of overlap. (The TR-6
should be so lucky) The rods were the weak point of the GT-6 engine
after they put on the TR-6 cylinder head. The damper is probably a good
thought but torsionals in that engine were never a major worry. We
turned to 8000 and made over 180 bhp at 7700 on the standard (ho ho ho )
Stromberg carbs. Making the rotating mass lighter is almost ALWAYS a
good idea.

This actually increases the rotating mass. Would lightening the flywheel
