Questions About Piston Design
In a late Bus did the pistons need to be as big and heavy as they were? I’m a machinist, and I see modern pistons, with thinner ring packages and shorter compression heights that could fit with some cylinder boring/honing. Because of the loads and head temps, were those bulky pistons used to survive the demands of the underpowered engines? Would lighter weight pistons work better?

Re: Questions About Piston Design
If you were trying to build a Race Bus then lighter pistons would be helpful.
They make the stockers strong because they rev low, and take much heat abuse.
Some run the KB hyper pistons in a bus at 96mm if they are feeling like pushing the reliability envelope..

That was the they were made with the technology/cost/metallurgy of the time. The same reason the dashboard has a total of two warning indicator lamps and no support for phone/map/messaging
I'm sure slipper skirts and thin ring packages wouldn't hurt

Yeah some may call it overkill, but you can't have too much overkill.
