I understand to beef up the engine from the IO-360-K to the IO-360-KB
(2000), one needs a stronger crankcase and crankshaft.

Costs?

Differences between the years:
The FAA TCDS 3A17 page 20 shows the IO-360-KB commenced installation in S/N
R1722930 - thru to 3454 (ie from year 1979-1981).

I cannot see any other differences other than TBO.

Why are peoples thoughts on a FADEC installtion, when approved for that
engine?

regards
Ron

TBO number is just a recommendation for USA CFR 14 part 91 operations...
