Hell, Dodge HEMI’s have been doing that for the last few years, it cuts back to 4 cylinders when cruising.

Wife had an 81 Seville, bought as a two year old car from the Caddy dealer in Mpls. The 8-6-4 feature was ruled by an electrical connection to the transmission, which the first owner had defeated.
Five years later when the tranny required service, the dealer plugged in the wiring and wife discovered how awful it was to herd a 5000 pound car on 4 cylinders.

Yeah, and we all remememer what a stunning advance that was.

There are some things Detroit should buy up and bury.

Our neighbors had one of those engines, it was about the same year my dad bought one of those gas/diesel conversion engines in his new pickup.

There wasn’t many nice things said about GM over the fence line for a few summers...
