"LA" engine?

All of the Chrysler small blocks are "A" engines until 1964 when they introduced the 273. That engine is an "A" engine that was "Lightened" hence adding the "L" in front of the "A" designation.

The "Poly A" 318 was in production until 1966 here in the states. '67 in Canada.
After that, all small blocks are "LA" engines until the Magnum engine came out. 92/93.


Unless you have something that says otherwise you are incorrect.

The "L" in "LA" engine is for "L"ate A engine, as the early poly stuff were already "A" engines. That's why the lifter bank angle is retarded...Chrysler used the cores from the Poly stuff.

Unless you have proof otherwise "L" does not mean "L"ight.

And magnums are still considered "LA" engines.
