Has anyone installed their Lyc 540 engine yet? I need some measurements. My plans show the 4 cylinder Lyc mount, not a 6 cyl mount.
The measurements I need are for the 6 cyl 540 Lyc;
How long is the mount from the firewall to the mount pad.
Or if your engine is mounted, from the firewall to the lifting engine eye (or the engine CG). The engineering formulas mass/moments are not close enough. I have to run several W&B scenarios.
Thanks for your help.

Here is the Jacobs that I'm installing. It has 400TT when removed from an AgCat to install a P&W 450.
