Thank you, Skip ________________________________ Message 2 _____________________________________ Time: 11:30:17 AM PST US From: "BPA" Subject: RE: Engines-List: Re: Lycoming engine designations Skip, A narrow deck engine will have 'internal' splined nuts, or nuts that will require a wrench that allows you to torque the nut from the inside versus a standard hex nut configuration. Another way to tell is the narrow deck engine will have retainer plates, 2 per cylinder. This is to allow for a thicker torque surface. The wide deck engine does not have these plates. The narrow deck engine has not been produced NEW for several years now and are getting difficult to find. Personally speaking, I prefer the narrow deck cases over wide decks mainly because the 'thru' studs screw into the case halves versus 'body fit' thu bolts as on the wide decks. An 0-360 A1A is a parallel head carbureted engine whereas the IO-360 A1A is a angle head. This being said, yes it is possible to convert one to or from the other, but it's not very cost effective. There are several parts that will need to be changed such as cylinders, push rods, push rod tubes, rockers, baffles.

You have an old style narrow deck engine. First series 140-150 HP engines did not have the plates. Second series, or phase 2 narrow decks did. These require longer deck studs to incorporate the plates. If I'm not mistaken this is a Service Instruction and most crankcase repair shops will upgrade the cases when they do the overhaul on your cases. If they didn't and you want the upgrade, call them and ask for the longer deck studs. I recommend the upgrade. There was another short lived case series that no longer is in production as well called the 'mid deck' but this is for another discussion.

The issue is this...the original Bellanca exhaust used a V clamp on the tailpipe/header joint and I'm having that modified to a ball joint w/triangular flanges and bolts/springs as the retainers, similar to the mod the Bellanca factory made around '76. My problem is the "factory" no longer really exists and parts/specs are unavailable, even from other Bellanca specialists. I have the bolt length/size but don't have the spring specs and they're no longer available. I'm told that these are probably the same as used on Cessna 210 and 206 models. Anyone have the spring part number or specs? Also told that these are Wall Colmonoy 650K ball kits but haven't talked to them to see if they included the bolts/springs or just the joint kits. Thanks.
