my engine came out of a 1964 Mooney, IO 360 A1A not too sure on the suffix number codes like some on here, but mine was rear prop governor, equal length intake tubes, l and r Bendix mags, angle valve, Dynafocal mount, CS crank, fuel injected, took all that off and went EFII. The narrow deck angle valve was about 2 1/2" wider than a parallel valve, but the SJ cowl fit with a 3" saber prop extension..............barley.
