Driving instructor Bob Reed had a stroker A-body without cage with a little less hp/tq than the Red Brick 68 Valiant (~550/550)
The Red Brick has 519hp/506 ft lbs, but who's counting?
Regardless of the actual power numbers, I'm sure that thing absolutely flies
The Brick does fly (160+ mph) but it is brutal to ride in. If you want a modern car buy a modern car. Hard to beat 50 years of R&D by a huge engineering staff.
