There was a Corse under construction in Texas some years back utilising a GM derived High Feature V6, but I've lost contact with the builder.
No reason why not to use this engine I'm sure. If a Toyota V6 is now a legitimate power plant for a Stratos replica then so is any Alfa badged V6, whether it is GM derived or not.
Like you say 159 V6's must be getting more reasonable in price.
I know the early F40 gearboxes ( up to 2007?) suffered from bearing failures and selector/synchro problems, so maybe something after that date would be worth hanging on for.
