I still think it was damaged BEFORE it was put in the box as cardboard doesn't scratch aluminium ;)
A quick note to anyone having pistons coated it needs to be done AFTER the block is bored and honed.
The issue being you don't know how uniform or thick the coating is on each piston so when...
I've just done the whole "musical turbine housing" thing with my T04z and can understand Figgie's PoV 100% and wouldn't run a mismatch again.
a 42 with a tight AR while it may work on a low capacity engine will be a surging/choking horrible thing in normal use (ie: NOT steady state output...
I'd drain what coolant is left and park it.
Danger is if you refill it and it sits without running the coolant will gravity feed into the chamber them leakdown past the rings into the pan and trash the bearings on the next start.
Ditto here on Whiteline sway bars and Teflon Crankscrapers, I wanted them and was happy to foot the bill for the prototypes everyone else getting the benefit is a side effect.
What goes around comes around I jumped on the ATI Damper once it was available :)
Coolant was low enough in the engine so on the flat it was below the gasket surface, soon as you got it on an incline the coolant would run towards that end up past the gasket and into the chamber burn and miss.
The Bad news with all this is running it at all with the coolant that low is...

Maybe offer 2 WP pullies?
One "Street" One "Race"?
My biggest concern is for the lightly modded guys that have a less than perfect cooling system slowing the pump could be enough to tip them over the edge heat wise and 7M's are notorious for commiting HariKari via the Rad ;)
