I am looking at a 2.0 on eBay, it is supposedly out of a '75. The # stamped on the block is GC003297, all the other 2.0 engines I've seen start with GA. Any help to decipher this is appreciated.
Thanks, John |

GA == 73-74 US-spec 2.0
GB == 73-74 RoW-spec 2.0 GC == 75-76 US-spec 2.0 The GC made 88 HP (DIN) as opposed to 95 HP (DIN) from the GA motors. The primary difference was the exhaust, which was pretty awful on the late cars. The GB made 100 HP (DIN), primarily due to higher compression. --DD |

Although I'm trying to find the documentation for where the California 75-76 GC only made about 80-84 HP that I remember from when I test drove them new back in the day. Also, you can put Euro P&Cs on any GA & do the requisite EFI adjustments for 100 HP for an easy power bump, as was commonly done back in the day. I'm not sure if the GC can be built &/or tweaked to make 95 HP, but if it's a 76 it may not pass CA smog required on them still every other year. Bottom line, the GC code is correct for the one you're looking at, but don't bank on anything conditionwise without driving it in a car, or running it on a stand & doung all of the compression & leak-down etc. tests - otherwise it's just a core which may or may not be usable pending tear down.
