The engine began life in a 1967 Cessna 172, and was replaced on an STC to
install an O-360.

This engine has higher compression pistons available, in order to bump the
horsepower up to 160 hp, however it would then be limited to using only 100LL
fuel.  I want to maintain the option of using  MoGas, therefore I'll keep it at 150 hp.
