Pretty sure you're right on this ^^^^. My older brother was the service manager of a nearby Pontiac dealer in the late 80's / early 90's. The last gasp of those cars was the turbo version with the 4.3 V6, which is 2/3's of a SBC. They were very limited production and at that time amongst their contemporaries, they were no joke. They had so much potential with small mods. They way outclassed the closest competitor Buick Grand National that had a smaller ( 3.8 ) engine and weighed @400 lbs more.

I came close to buying one, but at the last minute had reservations about affording that as the economy in late 1990 was just starting to tip downwards.
