Late Uncles Inland M1 Carbine. Still teaching my boys.

Is WCC M1 ball ammo in 600 round spam can good as the LC ammo? All non corrosive?

WCC is Western Cartridge Company. All USGI ammo was loaded to the same specs. All USGI ammo is non corrosive. You will pay a premium price for a sealed spam can of any USGI due to collector value. If you want shooting ammo then why not look at commercial ammo, there are some decent prices on PPU (Prvi Partizan) ammo from a number of venders right now according to ammo seek.
