Hello all, In the early 70's I was attending a Pontiac class at the G.M. tech center in Warren,Mich. The instructor told me that George Delorean had a shop a little north off of rt. 75. I called and George said I could come by after class.I drove up and found Leader Automotive .He gave me a tour and showed me a lot of parts I never knew existed. There were aluminum blocks,small chamber S.D.455 heads, forged cranks, and RAM V parts. There was a mock-up V engine with V intake flanges and a ford tunnel port 2 four barrel top they were mating together for a customer. If the instructor hadn't sent me I probably wouldn't have got past the counter.
