Default Lycoming vs. ECI vs. Superior?

I am shopping for a 6A/7A with an I/O360 and note that engine choices among the flying aircraft are Lycoming, ECI, or Superior. If I have an ECI or Superior engine, in the event of needing parts (repair, overhaul, etc.?), will Lycoming parts be interchangeable with the ECI/Superior?

The ECi and Superior engines are made from PMA'ed parts. Meaning they are essentially Lycoming clones but without the data plate.

In fact, my ECi engine is assembled using the Lycoming overhaul manual.

Just be aware of any AD's and SB's that apply to the potential purchase and see if any you are looking at buying are affected.

In every single In most cases....yes.

If you buy a Superior engine (or ECI, or Lycoming) why not just pick up the phone and call the respective manufacturer for any needed replacement parts? You can purchase piece parts from any of them.

If you're "in the field" needing emergency replacement parts, and the local shop only has genuine Lycoming parts, refer the first line.

ECI is now delivering assembled engines. I had the opportunity to first flight a 370 stroker (205hp) in a 1124lb RV-6 yesterday. Its quite an engine. Smooth, powerful. The best power to weight in this cost class as far as I can tell.

The ECI option looks interesting. Would love to check out the 370: 205hp.

I tried sending them an email, requesting a quote. Still no response after over 2 weeks. :-(
