Correctness of Our Specifications


Ultimate Source for Correct Information:

We're working hard to make sure all the stats on this website are correct. According to extensive research, we know we're right. Most books have some errors. At the bottom of this page, you'll see a list of common reference books and why THEY'RE wrong.

If you want to dispute any stats, just leave me an email and we'll research the correct information and add the results to this page.

The UltimateGTO.com Stats Explorer (tm) is a single correct source for information, verified from multiple sources. Unlike printed sources, we add and correct information on this site every day. Printed sources may not have been correct for 10+ years.

Remember that not all items available on the general Pontiac line of cars for a model year were available on the GTO. For example, the GTO was not available in every Pontiac paint color every year. There were a specific smaller set of colors offered for the GTO. Several sources incorrectly show a standard Pontiac paint chip list as the available colors for the GTO. No way.

Thanks to Eric White for helping with vinyl and convertible top letter codes. He is the author of The GTO Association of America's Pontiac GTO/GT-37 Illustrated Identification Guide.


List of Some Incorrect Sources:

Catalog of Pontiac GTO ID Numbers 1964-74 by Cars & Parts Magazine, Published by Amos Press Inc. 1993
   1969
      Exterior paint color Carousel Red (code T) is missing
      Does not list paint color of Goldenrod Yellow.
   1970
      Exterior paint color Orbit Orange (code T) is missing
      Incorrectly lists paint color Goldenrod Yellow (code W).
   1972
      Incorrectly lists paint colors Antique Pewter, Cumberland Blue, Julep Green, Arizona Gold, Spice Beige, and Cinnamon Bronze
   1973
      2-Door Hardtop listed as F in the VIN decoder and D in the Data Plate Decoder (F is right)
   1974
      Interior trim code 542 is listed for white vinyl for all white bench with white trim and bucket and for bucket with white, red or green trim. How come the white bench with red or green trim is 544? I think it is an error. (I bet 542 is correct for all)
      VIN decoder only talks of "Y" Ventura model, while Data Plate decoder talks of both "Y" Ventura and "Z" Ventura Custom
      Talks of both a wide ratio M20 and close-ratio M21 manual transmission. No one else does.
      Incorrectly identifies the VIN engine code as K which was corrected to B in a Dealer Service Information Bulletin (#74-I-14) dated 11/12/73. Info from Eric White.

      Does not list the 3.31 rear as an option for the 455ci automatic
   1971
      Production totals for GTO convertible and Judge hardtop swapped
   1972
      Peformance data for Motor Trend test is a 200 hp 455 with a 2 speed manual (300hp 455 with a 3 speed manual is right)

      Does not list paint colors of Verdant Green and Burma Brown
   1974
      Incorrectly identifies the VIN to have a N in the fifth digit for 350ci 4bbl engine code as the only engine in the GTO. N is for the single exhuast version. It should be B for the daul exhaust version. Info from Eric White.
