Early 1990's build with Muscle Motors turned down 440 crank, 440 rods, ROSS dished piston, and Koffels B1-B/S heads (Unported) using Mopar M1 4150 single plane intake. Used a mild Ultradyne solid street roller 251/251 @ 0.050" duration, and I think about 0.600" lift?

In the 4,150 lb Charger set for street driving, and at Bandimere Speedway (DA usually way over 7,000 ft) would run consistent 12.5 @ 110 MPH.
Took it to Las Vegas, and off the trailer, no tuning, went 11.8s @ 115+

This was with 3.91:1 gear, 3,500 stall converter, 10.5"x27" M/T Street ET tires.
