This 1970 AMC AMX is a rare gem, one of only 4,116 AMXs produced in 1970. Out of those, only 114 were painted in Big Bad Blue (BBB), and a handful received the sought-after Shadow Mask (-8) paint treatment. Originally, this AMX was a 360 Go Pack car, but it has since been upgraded with a high-performance .030 over 401 engine built by a renowned AMC racer.
The 401 engine delivers an impressive 525-550 horsepower, thanks to meticulous modifications. Key upgrades include:
Ported and polished heads
Forged steel crank
H-beam rods
Forged aluminum 10.5:1 pistons
Comp Cams mechanical roller cam with SS roller rockers and stud girdle
Edelbrock R4B aluminum intake with AMC PN
Holley 770 carburetor (fed by the factory Ram Air system)
8-quart oil pan
Edelbrock HD aluminum water pump
Aluminum 4-row radiator with custom shroud
These modifications help the engine deliver outstanding power and reliability, making this AMX a true powerhouse.
Power from the 401 engine is sent to a built 700R4 automatic transmission with manual lock-up. The power then transfers to the Twin Grip rear end, which features Moser axles and 3.15 gears. This setup provides excellent acceleration and a smooth driving experience, making this AMX both fast and dependable.
The Control Freak Suspensions front and rear coilover conversion systems provide superior handling. In addition, Aerospace Components equipped the car with 4-wheel cross-drilled and slotted disc brakes, ensuring powerful and responsive braking. These performance upgrades enhance the driving dynamics, offering a smooth and confident ride on any road.
The interior of this AMX is as refined as its performance. It boasts:
New leather Recaro seats
Restored Rim Blow steering wheel
Custom stainless engine-turned dash
Sony AM/FM MP3 sound system
Cruise control
Air conditioning (now using 134a refrigerant)
The cabin is both luxurious and functional, with added sound deadening insulation from the firewall to the trunk for a quieter ride.
This 1970 AMC AMX sits on 17-inch custom 2-piece Magnum-style wheels, adding a modern touch to its classic look. The Big Bad Blue (BBB) paint shines beautifully, and the Shadow Mask (-8) treatment makes it stand out.
Additional features include power steering, power brakes, and A/C, making this car both comfortable and powerful.
From top to bottom, this 1970 AMC AMX is a magnificent machine that combines classic style, raw power, and modern upgrades. If you’re looking for the finest, fastest, and most desirable AMC, look no further.
