| 273 CID LA |
The LA family of engines with its thin wall casting technique was introduced in 1964 with the
273. The new casting was much lighter and considered to be well ahead of its time. The new LA
block would be the foundation for many great high performance engines and is still in production
today.
The first LA was the 273, with a two barrel carb, and 180 hp (gross). By 1965, a four-barrel
carb and high performance cam were available to push that to 235 hp; and, in 1966, a limited edition
273 with a 700 cfm carb and .500" lift cam put out 275 hp (gross). This engine is known as the
D/Dart 273 and was built specifically to allow the darts to compete in D-Stock drag racing. It is not
known for sure if any of these 275hp motors were put into barracudas.
