C3 Production Numbers

Posted by Matt on March 12, 2010 • C3 (68-82), Corvette Production Numbers0 Comments

78_Silver_Anniversary.jpg

This week we’ll continue our look at Corvette production numbers through the generations with the 1968-1982 models.  This 14-year time span was the longest for any Corvette generation to date.  Corvette team designers did a commendable job freshening the car from it’s early “chrome bumper” stage from 1968-1972 periodically until the final, lower production (in anticipation of the C4) 1982.  Notable models during this generation include the competition-ready 1968-69 L88, the well-balanced 1970-72 LT-1, the last convertible model until the introduction of the C4 (1975), the base model 1976 Corvette with only 165 emissions-controlled horses, the Silver Anniversary (pictured) and Indianapolis Pace Cars of 1978 and the hatchback-glass equipped 1982 Collector Edition.

1968 9936 18630 28566

HVAC Odor Technical Service Bulletin

Posted by Matt on March 4, 2010 • C4 (84-96), C5 (97-04), C6 (2005+), Interior, Tech Tips0 Comments

IMAGE_413_detailWhile we know it’s not the most exciting topic to discuss, we are aware of this issue through several Q&A magazine sections and forum postings.  The problem centers on a musty odor coming from the vents whenever the A/C is activated.  The odor seems to diminish after a short time, but recurs after the car is shut off and restarted a while later.

More often than not, the culprit seems to be microbial growth on the evaporator core caused by condensation.  In humid parts of the country, the condensation doesn’t seem to evaporate on its own.  A plugged HVAC drain may create the same condition on the evaporator core.

Fortunately for owners of 1993-present GM cars and trucks (including Corvettes), there is a Technical Service Bulletin (#99-01-39-004C)  that remedies this condition.  It is a complex job, so it is recommended that a certified GM technician performs the work.  However, if you’d like to attempt the procedure on your own, we have the TSB below.

Corvette Racing’s contributions to the ZR1 and Z06

Posted by Mike on March 4, 2010 • C6 (2005+), Corvette Central, Corvette Racing0 Comments

Click on the pic above for an informative graphic depicting how Corvette Racing’s engineering and development efforts trickle down to the ZR1 and Z06 Corvettes.  Very cool.  Although for what it’s worth, the 1953-62 Corvettes were sporting exposed headlamps too…

Meet the Grille Teeth that Started It All

Posted by Matt on February 19, 2010 • C1 (53-62), Corvette Central, Corvette Culture0 Comments

yb.dll

In the near future we’ll be showcasing some Corvette parts that we manufacture at our facility in Sawyer, Michigan.  But for now, here’s a little history on our first parts ever offered by Corvette Central: the 1953-60 grille teeth.  Company founder Jerry Kohn: “Our first parts were grille teeth for the 1953-60.  To know why this was more complex than it sounds, you have to know a little bit about the 1953-60.  There were five different size teeth for the grille.  But Chevrolet did what they normally did to service parts like this…they made three basic sizes (center, tooth #4 and tooth #1, but not teeth #5 and #6).  This is what they catalogued as service parts.  Well, of course they weren’t right and if you had to replace an entire grille it just wouldn’t look right.

“There was one person, at that time, who made some solid aluminum teeth but they weren’t very good either.  So I had to find myself a good set of original teeth as a start point.  I had a little bit of trouble even finding a set.  I used to travel a bit to Cincinnati on casting business (Jerry once owned a company called Kohn Kastings).  On one trip I stopped to see a guy I met in Indianapolis who had a real choice ‘57 grille bar with a full set of original teeth…

“That’s basically how it happened.  I needed grille teeth and I assumed that someone else would.  The difference between what I did and what other products were available was that I got a full set of original pieces, made a complete set of molds and did quality castings.  We didn’t do slush molds or cheap ceramic molds.  We did it right.  It was as close to what GM did as you could make.

Those original grille teeth are still manufactured in Michigan as part #421006 (1953-57) and #421106 (1958-60) and they are included in a mix of over 3,000 parts that we currently produce.  Stay tuned for more history on Corvette Central exclusive parts, and the production processes behind them.

100_3407The following is an engine swap workshop guide that was produced by Chris Petris (www.petrisenterprises.com) in cooperation with Corvette Central, with assistance from Jared Ochs of Current Performance (www.currentperformance.com), and Chris McDonald of www.mcspeed.com.  Developed in conjunction with GM Performance, Corvette Enthusiast, TCI, Holley and Vette Brakes & Products.  Photo credit: Chris McDonald.  We will share with you our experience in upgrading our 1985 project Corvette to a 2007 LS2 with a 4L60E automatic transmission. Our workshop includes discussion of some common tools needed, modifications necessary, fabrication required, and part numbers for the components to complete the swap. Many of the considerations to complete the swap into a C4 would also be pertinent to other generations.
