You are correct, except his title states, "320 engine mount with 360...". Thus the longer engine mount and heavier engine with a light prop might just work out fine.
I'm not sure what the length difference between the 320 and 360 mounts are but I do know the mount I had with the 290 was 12" from the firewall. The mount I now have with the 360 is only 10" from the firewall.
Granted my -9 is different than the -7 but the O-360 and Catto prop with the 10" mount work out great!
