I had to acquire a new parts manual for the O-360-A1A. Since I am converting the cases from the Narrow cylinder flange to the Wide the parts manual must be updated.
Narrow PC-106 Wide PC-306-1
For the most part 75% of the narrow A1A is inter-changable with wide A1A... The exception being the cylinders, cam and a few mounting brackets.
I have a local cylinder shop that will swap my cylinders at normal core exchange or I may just purchase OEM from Lycoming.
I will have to buy a cam kit... included with new tappet bodies...
Lifters, pushrods / housings, accessory gears / case, sump / carb, intake / exhaust tubes are the same.
