Michael,
Installing the carbs & matching manifolds should certainly increase
power some. Especially with the accompanying cold air box. A good three
tube header & exhaust system would balance things out for even more power.
As far as I know, the factory installed LeMans cams were done with the
engine in the car. Original 100M cars had a slight bend in the radiator
front X brace to clear the cam on removal. If you do change the cam be
sure to use new cam followers & have ALL of them hardness checked for a
hardness of no less than RC50 to 55 at a machine shop. Use the M
distributor if you change the cam, though I doubt if it makes much
difference.
You can see pics of the X brace, air box clearance modification, &
quite a few other interesting things here:
