Back to the engine. I had a mishap and damaged a couple of pistons spitting them out of the bottom of the bores while changing to softer valve springs. Had a chat with Furey and the boys at Lonsdale engines. New hyperutectic pistons and rings are on order #$%^&*. They can't buy single pistons.
Furry said the chromolly flywheel and clutch will be fine. He questioned the need to use softer springs to run the cam in as mine aren't that heavy anyway, I don't know. He blamed the failure on lack of zinc additive and bad luck.
So I will just hone the bores and reassemble. Run in with the soft springs. I will measure the deck height and look at getting my small chamber head done up to suit for more flow and comp. Just larger inlets and a slight port radius.
All nice and clean at least.

While I'm waiting I can change the booster over. Next job.
