340 cam

It's driving me crazy; no ridge on the top of the cylinders new timing chain.. why can't I remember this engine? 727 going in in the am. Get that done, head helicoiled, I so don't want to pull the timing cover back off, and find the cam is not retarded, etc; and have an unknown trans in it, trying to get fluid right, and break in a new cam at the same time. Sigh.
