This is Savage X4.6. What is the difference between the F4.6 and K4.6 engines?
The important point is, are they compatible with the engine's piston and cylinder parts?
And please recommend a good engine to replace the original engine.
Thank you

Maybe the piston and sleeve are not shared?

Different manufacturers and specs, never heard anyone swapping parts.

I don’t think much of the K4.6 is compatible with the F4.6V1 or V2.

However the F4.6v1 and v2 have several interchangable parts. This is a good video illustrating:

K and F are not interchangeable. F4.6V1 and F4.6V2 are identical except for the crankcase and heatsink head. internals are identical.
