Not sure of validity of this, but does mention 807HP And it does say MY 2020. So not sure if these are old articles that are popping up.

2020 Dodge Challenger SRT Super Stock Overview
The limited-production Dodge Challenger SRT Demon was essentially a drag racer for the road, but it hasn’t been in production since 2019. For the 2020 model year, Dodge has expanded the Challenger SRT range with the new drag-racing focused Dodge Challenger SRT Super Stock. Essentially, this is a spiritual successor to the Dodge Demon.
Billed as the world’s quickest and most powerful muscle car, the Dodge Challenger SRT Super Stock is named after the Super Stock drag racing class. It’s powered by the same supercharged 6.2-liter HEMI V8 engine as the Challenger SRT Hellcat Redeye with an increased redline from 6,300 rpm to 6,400 rpm and an increased power output of 807 horsepower and 707 lb-ft of torque on pump gas, which is 10 more hp than the standard SRT Hellcat Redeye. To help it dominate the drag strip, the Super Stock features a new suspension setup and 188inch wheels wrapped in massive 315/40R18 Nitto NT05R drag radials at all four corners.
0-62 mph in the Super Stock takes 3.25 seconds, and it will also do the quarter-mile in 10.5 seconds at 131 mph and reach a top speed of 168 mph the quarter-mile in 9.54 seconds, making it the fastest muscle car currently in production.
Other drag-specific components and tech include launch assist, race cooldown, a real-time dyno graph and g-force heat map, and an ‘SRT Power Chiller.’ Unlike the Demon, which was limited to only 3,000 units, production of the Challenger SRT Super Stock will not be limited, so it will still be available for the 2021 model year. Orders for the 2020 Dodge Challenger SRT Super Stock will open this summer before customer deliveries start later this year.
