Often over looked is the first year AMC products. AMC invested approximately 300 million dollars in advanced engine designs, bodies and plant facilities as it prepared for the move from Nash Rambler hold over to AMC proper.
Of course the company was formed from Nash Rambler (AMC Rambler) in 1958 and eventually just American Motors Corp. So 1966 found a fair amount of “redesign” going on. The available models for that year were:
Rambler American Rouge Series 01 (4dr w/V8)
Rambler Classic 770 Series 10 (2dr conv w/V8) (4dr station wagon w/6cyl)
Rambler Rebel Series (2dr w/V8)
Marlin Series 50 (2dr w/6 or V8) (My favorite besides the Javelin)
Ambassador 990 Series 80 (4dr w/V8)
Rambler Ambassador 990 Series 80 (2d conv w/V8)
Rambler Ambassador DPL Series 80 (2dr w/V8)
Gone from the engine line up is the 196.5 6 cylinder overhead valve engine. It was replaced with the 198.8 In Line Six. It was a cast iron block with overhead valves and a bore and stroke of 3.57 x 4.00 inches. It displaced 198.8 cubic inches with a compression ratio of 85:1 and mustered up 128 hp. It was topped with a 1bbl Holley carb. This was the base engine and all of the models could have been optioned with it. But that wasn’t the only 6 banger the American 232 cid with produced 155 hp which sported a 2bbl Holley carb.
On the V8 side of things there was the 287 cid. It was a cast iron block with overhead valves with a bore and stroke of 3.75 x 3.25 which produced a compression ratio of 8.7:1. Topped with a 2bbl Holley (model 2209-2699) it made 198 hp. The other option was the 327 cid that put out 270 hp and carried a 4bbl Holley on top.
New for that year was the 290 V8 (4.8L) it had a bore and stroke of 3.75 x 3.28 and with an iron block and overhead valves which produced 200 hp with a 2bbl plopped on top for 225 with a 4bbl carb. Snap up the car with an original 290, only 623 of these engine were place in the 1966 models (all may the “American” models vs the “Classic” (those should have 287 instead).
The 327 was available in 1966. It was 5.4 liters with cast iron block. The bore was increased over the 287 (they were similar set up) and it had hydraulic lifters.
The AMC 327 was similar to the 287, but displaced 327 cu in (5.4 L) due to the bore increase to 4.0 inches (102 mm). Unlike the 250, the 327 was available with hydraulic valve lifters. The bore and stroke was 4.0 x 3.25 and topped with 2bbl carb it produced 250 hp. Put the 4bbl option and you push it up to 270 hp.
I really these early AMC.
Thanks for reading.
