We put the 440 in a '72 Satellite with 2.46 gears. It drove mellow around town like a grandma's car. However on the highway it was getting warmed up around 90 mph. It made 450+ lb-ft of torque from 3,200-5,200 rpm. The factory 318 suspension was somewhat loose, so that was plenty fast enough in that car.
The 451 with 906 heads did 554 RWHP in a '71 Road Runner.
The '72 Demon, with a Duster front end, had a 500" wedge with Edelbrock Victor cylinder heads and made 696 RWHP.
