Is there such a thing as a 5000 stall converter that is streetable ?

Yeah the four speed knob was the giveaway , but....
Buick ,in the sixties, had an electrically switchable stall speed converter for the 400 turbo. A friend put one in his 383 Vega. Nice and tight on the freeway, stalled almost 4000 at the flip of a switch. Wired it up to tighten up again in high gear. A great idea that disappeared for some unknown reason.

Keene-Bell switch pitch converter. Adapted from a Buick Dyna-Flow transmission. I like them, but it’s basically the father of the lockup converter. But, if someone would make new “switch pitch” converters for a lockup 904 or 727 (same mode of operation, only uses a variable pitch stator instead of a clutch) I’d be all for it.
