There’s a steam powered Grand Prix at the heritage center but it’s Pontiac so I won’t get into that, lol there is a corner of the back area full of engines on stands, I don’t remember if and Olds motors were there.
ill never forget walking the GM booth at the Texas State Fair, it’s the firest show of the season, and Olds was gone. A buddy used to be a set up Man for Olds at Stubbs, i wish I would have snagged some show plates. I snagged a few Pontiac things from Stubbs before it closed. I never thought to ask if any Olds stuff was still laying around. I heard the Ghost Pontiac was still in the whse at Stubbs when it closed.
( HB Stubbs had the GM auto show account for years, Creative Services was just Chevy, GM had that. They did close it at one point. )

Pontiac had hemis also. You gotta remember, the hemis and even the Cobras were not selling. They converted some super birds noses back just to sell. What no one wanted then is now rare.
