540 to 580 conversion for 300S

Post by Ace » Thu Sep 29, 2016 12:06 am

What all has to change to swap a 540 to a 580 in a 300S? Does it fit in the original cowling? Different motor mounts?

Has anyone done this on a 337 and kept the 300S certified?

I have an L1B5D with the dreaded death mag. If converting it to the dual mags is going to cost me an arm and leg I might just swap it for a 580.

Thanks!

Our 300S has been converted to the 580 and we have the original cowling. As far as I can tell the engine mount is the same, but I don´t know any details as the conversion was done long ago by the previous owner.
