Corvette Glossary


A glo ssary is an alphabetical list of terms in a particular domain of knowledge with the definitions for those terms. Traditionally, a glossary appears at the end of a book and includes terms within that book which are either newly introduced or at least uncommon.

This is our online version of Corvette jargon, specific terms, lingo, and much more. This is the Vettester Glossary.  Login, or register and submit your term to share them with all of us.

You can always search for entries (regexp permitted).

Term Definition
Date CodeAlmost every mechanical part made for a Corvette has a date code either cast or stamped into it. These are used to determine if the part is correct for that Corvette, as an engine with a date code of D 16 5 (April 16, 1965) could not be correct for a '63 Corvette as the engine was made after the car was made. Parts too early are usually not correct either, as they would have been installed on an earlier vehicle, such as a B 23 3 (Feb. 23, 1963) in a '67 Corvette. The date code on a SBC is typically on the belhousing flange behind the distributor. On early big blocks, it was on the passenger side near the pan rail, but later (1970) moved up to the same location as the SBC.
Dick GuldstrandDick Guldstrand was a Corvette racer from Southern California who pioneered several new ideas in Corvette racing in the late '50s and '60s.
DoghouseFuel injection plenum chamber, 1957-1965 models.
DOHCDual OverHead Cam - Two cams run over the valve train of the head. The cam either opens valves directly by the use of tappets (cam followers) or a rocker arm that rides on the cam lobes. The rocker method is least common. One cam operates the exhaust valves while the other cam operates the intake valves typically. With direct opening of the valves, typically there is room to operate two valves for the intake and two for the exhaust, so you have a four valve per cylinder engine. Typically this is in a crossflow head, where intake gases enter from one side and exhaust gases exit from the other. The advantage is that you can flow more air/gas in and more exhaust out, producing more power for a given displacement than a standard pushrod OHV engine. This type of valve train can operate at higher RPM than a pushrod style valve train.
Drag RacingA top speed or shortest elapsed time event between two cars on a straight course. Usually held at a drag strip of either 1/8 mile or 1/4 mile, each car starts when a starter (archaic) or a "Christmas Tree" releases them. The first car across the finish wins usually. See Brackets. In many drag strips today, there are timers at 60 feet to give times and there are lights before and after the finish to record the speed of the vehicles. These lights are called the traps. Some illegal drag racing is held on public roads and streets, often at a traffic light, where simply the fastest guy wins.
  A system of electronic accelerator activation to replace mechanical linkage. Corvette adapted drive-by-wire starting in 1997.
DuntovZora Arkus-Duntov. Chief engineer of Corvette for many years, viewed by many as the Father of Corvette. More realistically, he is the Step Father of Corvette as Corvette was already in production when he got there.
