Stupid things you have done

After spinning a bearing in my 67 coronet with 383, I did a "newfie" rebuild on another 383..... disassembled heads, sandblasted them..lapped valves, regasketed reassembled. Then me and a buddy Mike finally got around to dropping it in...all went smooth until firing up....would NOT fire for the life of us....2 days later another buddy dropped by, watched us with his hands in his pockets and told us quietly "big block distributors turn counter clock wise...." Re-ran the plug wires and BINGO!! Approx 2 minutes time........all with his hands in his pockets!!
