You are talking about teh commando? the interwebs says this: The 273 (4.5 L) was the first LA engine, introduced in 1964 and offered through 1969, rated at 180 BHp.

also I have understood that a 273 was is about the same as a base 318 or id concede 185--230 HP. Now a 340 can be tuned to right about 330-340 HP. Nicks garage spun one recently to

335 horse i think it was. I do enjoy the "little engine" arguments on here but i try not to get roped in too far with it.:) The 340 comment was a "yeah well my dad is bigger than yours" playgroundreference...:)

The 273 4 barrel that was in production between 65 and 67. Rated at 235 horse. Then of course there was the 275 horse D dart engine in 66.

""Tipping the scales at slightly over 2900 pounds, the 275-horsepower Dart fell into NHRA's D/Stock category-thus the car's appropriately fitting handle. Underhood, aftermarket parts included a 284-degree, ½-inch-lift Camcraft camshaft, Racer Brown valve springs, Doug's headers and a 4160 Holley carb adapted to the stock 273/235 iron manifold. A New Process A-833 4-speed gearbox was twisted by Weber clutch components and smoothly shifted by way of Hurst. Underneath, a "big car" 8¾-inch rearend carried a Sure-Grip center section and standard 4.86 gears. About the only items that this fleet factory rod didn't come with were air conditioning and a warranty."" (from an article in Hot Rod Magazine.
