Is there anybody that is familier with the alfa V6.

I want to start another project next to the avon.

An alfa Giulia with an alfa V6 transplant.
My questions is regarding the gearbox.
With gearbox can i use for this engine.
The only from alfa would be the gearbox from a Alfa 6 ( V6 and not transaxle)

I ve seen a transplant in the US with a Maserati biturbo gearbox ??

Any Idees

Alfa V6, what a sound.
