I voted O-360, but that's because I have an O-290, and I can't keep up with my son's RV-4
I'm always "shopping" for a conical mount O-320 or O-360...I would prefer not to remake the engine mount.
It looks like helicopter engines have conical mounts, so I wouldn't have to go with a 'Narrow Deck' enigne.
Hi Scott,
I just converted my "RVX" (6 fuse, 4 wings and tail) from a ND 0-320/Catto to a
0-360J/Catto. I too didn't want to swap mounts and researched Lycomings extensively to located the right engine at the right price. The 0-360J is a conical mount 0-360 with lightweight cyllinders and was installed in late model R22's horizontal mount with a MA-4SPA carb(0-320) and max RPM of 2550 (derated) Frank Robinson wanted to extend the TBO with lower HP but retain the 0-360 torque. I installed an MA4-5 (180HP carb)Vetterman (new design) tuned exhaust and a B&C SD8 lightweight alt and Skytech starter/odessey battery. The weight gain was less than 5 lbs over my 0-320. Cowling fit, baffling and mounting were very easy, the 0-360J bolted right up, my old baffling would have fit with few mods but the guy who bought my 0320 wanted everything FWF, so I ordered a new baffle kit from Van's and used the old one as a pattern. Hopefully you can use your old one. Email me anytime with questions.
smokyray@rocketmail.comSorry I missed prime time at OSH, had to work early in the week and arrived Saturday to volunteer at Itec's booth. I did get to watch watch a "mass Thorp exodus", sounded great!
