69 z28? Are you sure. I thought that they didn't start making z28's till the late 70's. I'm not being a dick, I'm just inquiring!!!
Someone in my family had a 1980 z28 with 350 from a corvette in it. Had an M-22 4 speed and a dana 60 rear. That shit was dope!!! Didn't lose to many races, nobody had a clue. Everyone thought it was stock, boy were they surprised when they got smoked off the line!!!
