Reply to "Pantera #9248 - 1982 GT5 - what was the OEM engine color?"

Martin, Gr-3 is a FIA international racing class and parts to allow your Pantera to comply with their competition rules are well defined. All Gr-3 parts could be purchased directly from DeTomaso Europe during about '72-'78. If the factory did the installation of the parts you bought onto your Euro-sold GTS Pantera, it would be a 'factory GTS/Gr3'. If you had the parts sent to your home or to an independent shop for installation, it may still a GTS/Gr-3 depending on what was done, just NOT factory done. And finally, you could buy only the parts you were interested in; that made it a GTS-with-some-GT3 parts. A few GTS/Gr-3s were further upgraded to legal GR-4s and competed as such.

To my knowledge, Gr-3 engines got a U.S.-made aluminum intake manifold and Holley 4bbl carb, a better set of headers (not the stamped-steel thing) and free flowing GTS exhausts. HP increased from maybe 300 to maybe 330. The Gr-3 catalogue (two versions known) has 18 pgs of parts.

For far more info, browse to www.scuderiadetomaso.se. The gr-3 site is maintained by Anders Hellburg in Sweden who owns a factory GTS/Gr3. Your serial # does not appear on Anders' factory Gr-3 List, nor on a later, expanded one.
