I'm a 911 guy and don't know much about the 928s. Have a buddy looking into one and the seller says the aluminum S engines were made by Buick! I told him the guy must be nuts. So...am I the uninformed or is this Buick thing somebody's myth?

Do you get a Buick price as well??

A good bedtime read is "Project 928", and you should get your answer.

There may be a myth there somewhere that I'm not aware of, but all 928 engines (or at least those that were in the cars when they left Zuffenhausen) were Porsche in-house designed and produced.

There are some 928's, even a few on this forum, that now have GM engines in them, but that's not OE.

Perhaps the seller is confusing the 928 engine with the Rover 3.5L V-8 that was originally designed by Buick in 1961 or so (?)

Here's the straight poop for your friend:

I heard they were originally made for Chev Vegas

The Buick /Olds and Rover alloy V-8 used ferrous liners. The Vega was alusil just LIKE the 928 block with all the same issues of needing "special" piston coatings , honing to size with the paste ,and being rather brittle prone to cracking because of the high silicon content.

OK guys, thanks for the info and the confirmation. Looks like you have a very comprehensive and well informed forum here.

Isn't a Buick the car you buy when you retire and move to Florida before you die?
