  7. Manta
    I thought I'd start off by saying this is my first post on this site. I've owned my first Opel - a white 1974 Manta Rallye - for about 4 or 5 months now and finally got around to pulling the engine out to have it rebuilt.

    INTRODUCTION First time poster, long time member. It's January 1st, 2016 and my new years resolution is to finally showcase the work that was done to my 1974 Manta. For all intents a purposes, this isn't a “how-to” but rather a “how-I-did-it” in regards to this engine swap. The project took...
