The photo In my first post was one of my bushings and one can see both the Lord p/n and the Van’s p/n as well. Several folks on VAF have reported conflicting information on ACS and other sites referring to them as dynofocal.

The J-6230-1 part number shows up on Aircraft Spruce and other sites as a Dynafocal mount.

Chief Aircraft has them: https://www.chiefaircraft.com/catalogse ... q=J-6230-1+

Almost as expensive as a Dynafocal mount.

Rick,

The Lord conical p/n:

J-6230-1

Hopefully this was visible in the photo in my earlier post. Four sets are needed, so be prepared for a bit of sticker shock.

Great to hear Brian, which model number did you use? I didn't realize that there are dozens of different model Lord bushings specified for certified aircraft.

Brian and Rick,

Appreciate the information.

Thanks,

Bill - Dan does recommend conical Mount lycomings for the Panther. Less weight, more firewall to engine space, less expensive mounts, and minimal vibration difference. Info is on the spa website. Will be interesting to hear what Brian finds out about the Lord bushings (don’t have my mount yet) Found a Midtime B2A 320 on Barnstormers for my Panther, good luck.

Bill,

I don’t have any details on the O-235’s (I have an O-320) but do know that Dan recommends the conical mounts as they are indeed lighter than their dynofocal counterparts. Furthermore, the older narrow deck engines are a few pounds lighter than the later wide deck engines as well. Every pound you leave on the ground makes a Panther more fun in the air.

Brian,

I'm off topic some, new Panther builder and have not bought an engine yet. Been looking at 0-235 & 0-320 on Barnstormers. Are the engines with conical mounts lighter than dynafocal and better suited for the Panther due to less weight?

Thanks,
