1972 402/454 Engine Production

Figures are for Chevelle ("A" body), Full Size Passenger ("B" body), and Camaro ("F" body) platforms and are broken down as such.

The LS3 is a 402 cid Mark IV engine listed as a Turbo-Jet 400 and was available on all factory V8 wagons, the standard Chevelle series sport coupe and pickup, all Malibu series body styles including the Custom El Camino. The LS3 was identified with '400' emblems on the front fenders the same as the '350' and '307' emblems. When an LS3 equipped SS-optioned Chevelle was sold, only the SS emblem was used on the front fender behind the tires and no engine size was designated. This is also true of the two 350 engined SS Chevelles and only the 454 engine received any engine size designations. See the how to identify a 1972 Chevelle SS page.

LS3 figures: The LS3 is one of 4 available engines with the RPO Z15 SS Equipment option. Chevelle and Monte Carlo figures for this engine are broken out in the table below. Therefore the LS3 figures for Chevelles and Monte Carlos include all sales of the LS3, not just in combination with the SS Equipment option.

LS5 figures: The LS5 engine required the SS Equipment option, the two 350 cid and 402 cid engines could be ordered without the SS Equipment option. A total of 24,946 Z15 optioned Chevelles were sold.
