IO-390

Curious as to why the newer model IO-390 depicted as the EXP 119 by Van’s
would be labeled IO-390-EXP239 on documents from Lycoming?
 
Number depends on options

if you keep the accessory case as original it is a different variant. Jeff at Lycoming can help you decipher . . .

My friend did have the vacuum pad opened up for a standby alternator. Thanks for clearing this up for him. We called Lycoming today but after waiting quite some time we gave up.
