How do I tell the difference between a wide deck and a narrow deck O-360?
Which is preferable?
Is an O-360 A1A interchangeable with other "A1A" or is there more that I
need to know?
Thank you, Skip

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.

The narrow deck has some type if clamps under the nuts on the base of
the cylinder.
The wide deck is beefy enough not to require them (i.e. the nuts hold
down the cyl. directly!)
do not archive

Allen, one question, I have a narrow deck engine
that is low compression , 7.4 to 1 0320 that doesn't
have the plates , and the info I got (older engines)
was that only the upgraded (ie: 160hp) engines
needed the plates.. can you tell me if some of them
didn't have the plates ?

Danny,
Boy! 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.

| Subject: | Exhaust ball joints...... |
--> Engines-List message posted by: "Jim Baker" <jlbaker@msbit.net>
I'm a Viking driver and am having a rebuilt engine shipped from
Cont. shortly. 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.

I have a set of Cessna bolts and springs and nuts I believe there is 3 of
each would have to look for sure. I will sell ,, Make me an offer ...Dale
