THE 1972 THIRD GENERATION CORVETTE

 

Welcome back to Hobby Car Corvettes, as we continue our C3 Vette Rundown Series. Two weeks ago, we discussed the underwhelming launch of the 1971 Corvette. If you missed the posts for all years prior to 1972, we do recommend checking those out! Short, sweet, and to the point, our series aims to give a brief but pertinent history of the lifespan of the third generation Corvette, from start to end.

 

Cruising right along, let’s see what changes the 1972 Corvette brings to the table!

NOTHING ADDED, MUCH REMOVED

 

Similar to 1971, 1972 brought us very few changes, possibly even fewer. There were virtually no changes, in the form of additions, made to the 1972 C3. The biggest changes were not additions of fancy or efficient features, but the removal of them.

 

The option of including the 454 cubic inch big block LS-6 either on its own or as part of RPO ZR2, was no longer available. This decision was made in response to incredibly poor sales numbers the previous year Only 188 Corvettes with the LS6 engine and an embarrassing 12 Corvettes equipped with RPO ZR2 were sold. This was the final year for the LT-1 engine and the ZR1 racing package built around it.

 

Though we mentioned it in the 1971 post, 1972 was the first year that no Corvettes were equipped with fiber-optics monitoring systems, headlight washer systems, and the M22 heavy duty 4-speed manual gearbox.

1972 did mark the “end of an era” within the third-generation Corvettes. The 1972 Corvette, was the last model to feature both front and rear chrome bumpers, a bright egg-crate grill, side-fender grills, and a removable rear-window. Later models do have functional vents and some have vent trim.

A RACING FAVORITE, EVEN WITH LESS HORSEPOWER

In response to the regulation changes in 1971, GM, like most other automotive manufacturers, began to measure engine outputs in the new SAE “net” for 1972. This change in how horsepower was measured was a notable change for C3 Vettes. This choice to use net numbers instead of the “gross” horsepower measurements came about because of the power losses. Prior to 1972, horsepower was measured on a blueprinted engine without any accessories such as the alternator, A/C, etc. In 1972, measurements were taken with all the accessories, which resulted in lower ratings.

 

This loss of classic Corvette power behind the wheel due to the mandated engine changes in 1971, was another notable difference. Despite the decrease in output, Corvette remained a racing favorite. In addition to being a preferred racing machine, tire companies also utilized Corvettes to test the quality of their tires. The combination of weight and speed common to the Corvette, demands a quality tire. Both Goodyear and B. F. Goodrich recruited Chevrolet Corvettes to put their tires to the test.

Goodyear won the unspoken competition through the exceptional performance of Dave Heinz and Robert Johnson. On February 6, 1972, Heinz completed the race for the team, placing them 8th overall at the “Six Hour Daytona Continental-World Manufacturers Championship Race”. Even more exceptional was the team’s GT finish and overall 4th place on March 25 at the “12 Hours of Sebring”. This was great press for Chevrolet Corvettes!

 

In addition, race car Driver at the time, Tony DeLorenzo, test drove the 72’ and had nice things to day. DeLorenzo was quoted, “you can’t get a better overall performance car.  I’d be hard-pressed to find a better car for the money, then the ‘Vette.

 

DID YOU KNOW:  

 

The “12 Hours of Sebring” Corvette fourth place finish amongst all racing classes that year was the best overall finish Corvette had ever seen to that point in its racing history.

 

Only three engines were listed for the Corvette in 1972, which made it the smallest selection since the 1956 model.

 

OVERALL… 

 

1972 was not an exciting or impressive year for Corvette. What was exciting, is that despite the changes in engine power, Corvette maintained its reputation for being fast and fierce! It was good to know, that even with restrictions in regulations, and the changes in engine size and power, Corvette was still Corvette.
