I believe I read that they used the 4160, which uses a vacuum secondary.  The 4150 has mechanical linkage...

My '66 with the 327/300 has the 4160.

OK thanks , is it your 66 have a manual 4 speed ?

Mine came with the B/W 3-speed automatic which I had replaced with a 700R4 GM which has a torque converter and overdrive.

OK , so mine too have the original automatic transmission , but i'm gone put a 4 speed T10 and i'm searching all information to do it right 😃

If somebody have an early Avanti II with 4 speed , i'm interesting about  under car transmission pictures 😊

Thanks
