However, last night at an EAA meeting, someone told me they heard narrow decks were no good, but could not offer why. I bought the engine from someone who had been building a 10 but lost interest, and I never considered the possibility that a narrow deck might not be suitable, but I'm not certain why that would be. Is a narrow deck C4B5 acceptable for a 10? I hope someone else has one...

Its a narrow deck. I fits the engine mount perfectly. The only thing I remember as being a question is which mounting tabs are on the engine. These are easily changeable if you have the wrong ones. One note, I'm not using Van's prepackaged firewall forward kit, I'm on my own for these various accessories. Also, I'm converting to fuel injection via the airflow performance conversion kit.

I don't know if Lycoming still makes major replacement parts such as crankcase. Cylinders should be no issue, along with most other standard replacement items. Lycoming stopped making new narrow deck engines about 30 years ago, but as far as I know they have been supporting them pretty well. In fact, they used a narrow deck engine for the certification mule of an IO390 in a Mooney 201 this year, as it was on display at OSH. If you can get a quality overhaul of the engine now, you should be good to go for 15-20 years. On the other hand, Lycoming has refused to take as cores for exchange engines of either variety that have not been back to the factory for overhaul within the past 36 years.

The engine may/may not have a lightening hole crankshaft which is fine but not suitable for aerobatics (shouldn't be a problem in the -10.) The cases have a number of overhauls that can be done by an approved facility and most of them will have cases if you ever have to replace them. The only difficult major component to replace at this time is the crankshaft. Used serviceable crankshafts are very difficult to find at this time, and new ones are very pricey. OEM flat tappets are also currently difficult to get but PMA are available. If the -C4B5 came from an Aztec, the mounts will be the larger hole and will need to be swapped to the smaller ear mounts. If you decide not to use it, let me know. I'll by the core from you! :-) Good luck. Rhonda Barrett-Bewley Barrett Precision Engines, Inc. 2870-B N. Sheridan Rd.
