Story
1966 AMC Marlin
For 1966, the fastback became the Marlin by American Motors. It retained the 112-inch Classic-based body and model 6659-7 identity, but dropped the 1965 car's Rambler lettering. Engine, transmission, axle, brake, paint, roof, and seating choices are configurations on this one model-year family page.
Five engine configurations
The standard Torque Command 232 six used a one-barrel carburetor for 145 gross horsepower. A two-barrel 232 raised output to 155 horsepower. Optional V8s were the 198-hp 287 two-barrel, 250-hp 327 two-barrel, and 270-hp 327 four-barrel. The last used 9.7:1 compression and premium fuel; the other four were regular-fuel configurations. A current 327 or four-barrel does not establish original installation.
Three-speed, overdrive, four-speed, and automatic
The factory selector lists a column three-speed, overdrive, a floor-shift four-speed synchromesh manual, column automatic, and console automatic. The new four-speed could be ordered with the optional two-barrel six and V8s. Published axle matching centered on 3.15:1 and 3.54:1 ratios, with specified 2.87:1 and 3.54:1 alternatives. Transmission case, pedals, controls, console, torque tube, axle, dates, and records should be evaluated together.
Torque tube, all-coil suspension, and two brake paths
The semi-floating hypoid rear axle remained inside the torque-tube driveline, with optional Twin-Grip limited slip. Independent front suspension and the torque-tube rear both used deep coil springs; heavy-duty springs and shocks were optional.
Standard brakes were self-adjusting 10-inch drums at all four wheels with separate hydraulic circuits. Power-assisted drums and power front discs were optional. That is an important model-year distinction: the 1965 Marlin had standard power front discs, so disc hardware on a 1966 car requires its own evidence.
American Motors identity, finish, and cabin
Marlin and American Motors identification replaced the 1965 Rambler branding. The brochure offered nine standard solid colors, 15 optional two-tone treatments, and a black vinyl-covered roof that extended over the rear deck. The model-year paint table contains additional colors, but the complete public Marlin-only compatibility matrix was not recovered; body-tag codes and protected finish remain decisive.
Standard seating was non-reclining and retained deep coil springs. Optional arrangements included individually adjustable reclining seats or reclining buckets with a console or center cushion and fold-down armrests. A dashboard tachometer, adjustable steering wheel, air conditioning, power windows, radios, and Turbo-Cast covers were also optional. Marlin trim suffixes M, N, and Q identify material paths, but the complete trim code must be checked rather than inferred from color.
Production and authentication
American Motors built 4,547 Marlins for 1966. No reviewed public ledger provides a reliable engine, transmission, axle, brake, paint, or trim split, so this page does not manufacture rarity claims from surviving cars. Authentication starts with the 13-character VIN and model 6659-7 body tag, then reconciles engine code and ID, induction, transmission, torque tube, axle and Twin-Grip, brake type, suspension, body and glass, paint and roof, trim code, component dates, original paperwork, and restoration history.
Price and market context
The published base price was $2,601 before delivery and options. One surviving 232 two-barrel three-speed car has a documented $2,838.40 equipped window sticker; that individual total is not a universal price schedule.
Dated market records deliberately separate six-cylinder, 327, three-speed, automatic, survivor, restored, modified, sold, and reserve-not-met subjects. The $99,000 custom-car result is labeled as a highly modified outlier, and repeat bids for the same car are identified. These observations provide history, not a current appraisal or proof of another Marlin's identity.
