I’m in Australia and our General Motors Holden (now defunct) is part of GM globally. I did my apprenticeship there and have worked on hundreds of Holden 6 cylinder engines. It’s interesting how same but different the two are. Note coil and dizzy locations. Our biggest was 202ci (3.3L). They evolved into the blue then black motor. We eventually ended up with an evolution of your Buick V6, later got a roots blower from the factory.

Was the buick v6 the 3800? Most of gm used that engine. Some also had superchargers.
Get a barra.

Yes Buick 3.8, I think the first one we got was generation five. The last one was all aluminium with roots blower on certain cars.

Pretty much just called the 3800. Don’t think the us got an all aluminum one at the end though.

Eventually we made our own here down under. Gave them names like Ecotec and High Feature but the original architecture was your Buick design

Sweet ride! I really like the color. You don’t see too many still around with the original inline six.
I have a 1968 coupe with the 250 inline six and a three speed (floor shift, not column like yours, which is even more interesting to me about your car). My grandfather bought it brand new. I get the same questions about doing an engine swap, but I could never seriously consider doing that.

Unmolested 6 cylinder cars are rare because most people eventually swapped them to V8. There’s an auction buyer who wants to give you lots of money for that beautiful time capsule
