Ignore the rest of this post as it is redundant - I had missed bkozlow's answer to this earlier in the thread. He answer is spot on.
Looked into DriftingCloud's motor with my camera bore scope. The "cam lobe" on a 351 Windsor is an external thing bolted onto the end of the camshaft. This particular engine was obviously intended for an electric pump as the the lobe for the camshaft was not installed.
Noted elsewhere in this thread that folks had referenced a lobe on the crank. Most definitely NOT on the crank. All Chevy and Ford V8's I've ever built have a lobe on the cam - but then I certainly have not built every flavor of Ford or Chevy V8 so I am only making a 99.9% assertion. Always leave wiggle room
All that being said, It isn't that big a deal to add the lobe if your engine does not have one.
