It depends on the engine you have and the engine you are going to install.
If they are both conical mounts (The bolts go in perfectly horizontal), then yes.
If they are both Dynofocal 1 mounts (The bolts go in at an angle), then yes.
With my RV-9, I started with an O-290-D2 and when I switched to a larger engine, the replacement mount was 2" shorter than what is used for the O-235 & O-290's.
So, while your engine might bolt up, your CG may be in the wrong place. Someone must have done this before. That or contact an owner with the larger engine, have them measure the distance between the firewall, and the back of the mount ring and compare it to yours.
BTW, going to the large engine in the 7ECA can impact your useful load.
