I am changing out cam on my '66 ragtop. The number stamped on the block is V0504WA. What does this mean?? I know this is not original engine. Just curious about numbers. Also stamped on left side of engine (looking at it from front) by port for water pump is the number 15661. On the right side is 090. Any ideas what these are? The engine is a 283. Thanks for your help. graemlins/waving.gif
