RV-3 engine question

[Wiley Price]

I just bought an RV-3 less engine. How can I determine what Lycoming model number will fit?

do you have an engine mount?

Or the logbooks?

As mentioned previously, you need to start with the engine mount. Did you get one with the airframe? If so, then you need to align your engine purchase with what you've got already; or a). get with Van's to purchase a different one, b). fabricate your own (A/C Spruce who sells "Dynafocal Engine Mount Rings & Kits").

Register your RV3 with Vans Aircraft and purchase the buildings plans, it will answer most of your questions.

If you create an account at Van's Store and register your aircraft with its serial number you will have access to the plans and service information online at no charge.

At a very high level, the RV-3 was designed and/or has been generally fitted with Lycoming engines in flavors of O-235, O-290, O-320 series.

With the exception of a few oddball models as well as the 0 320H series, all conical mount four cylinder Lycoming's fit the same mount and nearly all Dynafocal engines fit the same mount.
