Husqvarna L77 vs 480CD piston

[mojo jojo]

Hey,
does anyone know if the pistons from L77 and 480cd are exactly the same? I know they have the same diameter and displacement, but what about design (porting)
The same question goes for cylinders.

Not 100% sure on the pistons- or variations of piston through the production era- but pretty sure the cylinders are the same.

THX. If jugs are the same (porting and all), then pistons must be the same also.
I just watched youtube videos of complete rebult of L77 and 480CD and from I can see, the pistons look the same.

Well, I do not approve painting an old saw with spray can. That is a fail.

They're the same saw. The only differences are the crankcase fuel tank and top handle.
