The L30/M20 Camaros

The L30/M20 Camaros were built in 1967 and 1968.
They had the L30 275 HP/327, the M20 Saginaw 4 speed transmission, and most had the 12 bolt rear axle. In 1967 they had the factory traction bar mounting in place.  Some may have had the traction bar installed, this car did not.  In 1968 they had multileaf leaf springs to help traction.
Production figures listed in the quote below are for both years combined.

How Many...?
How many L30/M20s were built? While Chevrolet recorded how many of each individual option was built (for details on option production quantities, see the link to the CRG option spreadsheet), there is no traceable record of how many option combinations like the L30/M20 were sold. However, a source has provided CRG some as-yet untraceable information, supposedly from a GM production survey, that indicates that a total of 12,155 L30/M20s were built.¹³

To supplement the above as-yet untraceable production number, we can make an educated guess of production numbers, based on V8 engine and transmission usage, from the single option production data that is repeated in the table below. While the estimate could be approached from several different ways, the calculation below is made in the following manner: 1) Determine the percentage of L30 engines relative to total V8s engine. 2) Determine the number of M20 transmissions used in V8s (total number of M20s minus an estimate for limited number of M20 transmissions used on L6 cars - 2.7% of M20s, based on a sampling of data available to CRG). 3) Multiply the percentage of L30s by the number of V8 M20s and the result is a rough estimate of the number of L30s mounted to M20 transmissions. This two-year estimate of 11,029 is close to the unconfirmed GM production number of 12,155 L30/M20s. Depending on which number is used, L30/M20s comprised only 2.4 to 2.7% of all Camaros built in these years.

Production quantities this low put the L30/M20 on a par, quantity-wise, with models like the 1967-69 SS with the L78 396ci-375HP engine (9464 built) or the 1968-69 SS with the L34 396ci-350HP engine (4597 built), and significantly more rare than other very desirable production models like the SS-350 or the 1968-69 Z28. Given the relative lack of respect that this poorly appreciated option combination has enjoyed, these forty years later it is likely that surviving original L30/M20s are counted in the hundreds rather than the thousands.
