camshaft profile

[Lawrie]

I'm building a spare engine that is 276 ,I had to sleeve one cylinder as the block was bad on that cylinder,(C69a)
Looking out a better cam for it ,I checked a few in my pile, I have a nearly new stock one from a 99A , I mapped it out and then did the same with an EAC cam,( a bad one with one lobe messed up)
you can easy see the difference between them .
stock cam .303 lift with no clearance, EAC cam .327 lift with no clearance
I used valves with the head machined down to measure the cam lift and profile.
I dont have an early 33 steel cam(except for the one in my 34) so cant see what the difference that would be, but they seem to have better timing than the later ones, as the 34 engine is really nice.
I,m not smart enough to work out how much more area or air or whatever the difference in the two cams would be, but you can visably see it on the map
