Again, the only visual change
between the '72 Camaro and the '70-'71 was the egg-crate style grille. Once
again emissions and the oil crunch dropped performance considerably... the
hottest engine available in the Camaro was now the 255 net-horsepower LT-1 small block.
This was also the last year ever that a Camaro would carry a big block, the
396/402. From this point on the largest engine offered in a Camaro was a 350 cid
1972 was also the last year for mechanical cams (thank the government for that
again) as well as the Holley carburetor on Chevrolet small block engines.
Overall the 1972 Camaro is considered a rare car, because a 117-day auto worker
strike caused only 68,651 Camaro's to be built that year. Of those, only 930
were sold with big blocks, making them quite rare.
