273 Commando

The 273 Commando motor was the high performance version of the 273 LA small block V8.

It was rated at 235HP verse the 180 of the standard 273.

The Comando came with a solid cam (the adjustable rockers are popular for use in other LA builds), a single plane iron 4bbl manifold, 4bbl and a low restiction single exhaust. Where the standard 273 had a hydraulic cam and 2bbl intake/carb.

When the 318LA was introduced in 68 it produced 230HP with a 2bbl and the 273 was quickly forgotten.

NOTE: in 67 Mopar produced a limited production race version of the 273 Commanda rated at 275HP. It came with headers, bigger cam and a 700cfm 4bbl.
