1968 Camaro- 327, turbo 350 trans, 4.56 posi. I was 16 and THOUGHT I knew how to make it fast! Totally mismatched cam/intake/carb/converter/gear combo! It came with a 307 I rebuilt (absolutely unnecessary, but like I said I was 16) using an inch/lbs torque wrench that my dad had, not even realizing it wasn't ft/lbs. The head gaskets were pouring out coolant so I just tightened them down as tight as I could, got it running and drove about 2 miles until #1 and #2 rods went through the oil pan! That's when the 327 came into place. I look back and wish I would have left it alone, saved all the money I wasted on bs and just drove it and been happy with what I had. Hind sight is definitely 20/20.
