At TDC, the timing mark on the front cover will be pointing at the big notch
on the crank vibration damper (assuming the damper hasn't failed and allowed
the outer portion to rotate relative to the crank).
At TDC on the compression stroke for #1 cylinder, the locating pin on the
cam gear will be at the 12 o'clock position and the cam lobes for that
cylinder will be forming a V with the exhaust lobe tipped towards the
manifold side and the intake lobe tipped the other way.
If these don't match up, there's a problem.

Subject: [Roadsters] Engine in -- but no start -- hit list needed
All,
About two months ago my cam broke. At that time the car was running. I got
a new cam, and a new head. Finally got them in, and the car won't start.
I've tried what I think are the basics:
1) yelling
2) running the distributor through its swing to see if I could get a catch.
3) confirming spark
4) confirming gas pressure to the carb
5) confirming spark plug wire orientation
Here's where I'm stuck up.
I was pretty careful about keeping the timing gear at the same place on the
chain, but I'd like to confirm that I've not screwed the mechanical timing.
I still have some slack in the upper tensioner which makes it a little
difficult to see where things are. And -- since I don't know what the hell
I'm doing -- I could use a walk through about what top-dead on crank and cam
shaft look like (i.e. is TDC when the cam pully knotch is at the indicator,
or at 12 o'clock; and where should the cam lobes / gear orientation pin be
at that point?)
Another possible problem would be the SU carbs. I tried to store them
oriented properly -- but my brother shuffled them around the garage a
little/
Could I get the group wisdom on what what I should check and do as far as
diagnostics.
