318 Timing Chain Question.

Geez some of you need to take a Zanax....the feller said he cant see it from below because its a 46 custom something so, id figure do to dot would be easier to see even with a mirror. The distributor isn't out of the car so non issue there. he could either line it back up 12 and 12 the way it came apart OR dot to dot the distributor would turn with the cam on lineup p and the thing would start wouldn't even need to check timing etc. Only thing OP has to worry about is being a tooth off either way from not being able to see it straight on if that's the case... hey sorry I replied first wont happen again. To anyone else I say buy a book...it would be quicker to go to the bench look at it instead of asking on a forum :)
