Sorry for all the questions, but thanks alot for any answers!
I may be off a year or two, but that last 359s 86 and first part of 87 were ATA. I don't recall that 85s came with that option though.Trying to learn a little about the 3406 in my 359 Pete. The engine serial # is 7FB11795. It's a B model is about all I know. It's not an Air to Air so I thought it was an A model. When did they start air to air?
