Kelford 272s: symmetrical or not?

[soldave]

Wondered if anyone can offer a quick answer to this. Am working something out in my head regarding these cams and need to know if they are symmetrical or asymmetrical (i.e. do they open more aggressively than they close - excuse the huge simplification).

Does anyone know off-hand?

Hopefully the camshafts are symetrical to one another.

Hopefully the camshafts are symetrical to one another.

Not what he was asking, however, I don't know personally.

 

[ENICKB]

Asymmetrical - Having no balance or symmetry.
Symmetrical - Having corresponding points, whos connecting lines are bisected by a given point or perpendicularly bisected by a given point or plane.

Congratulations, did you get your engineering degree for that? His question is if the lobe on the cam is symmetrical from side to side or if it increases/decreases from the valve opening to the valve closing.

You can check this with a dial indicator and a degree wheel. If it is symmetrical the lift measurements will change at the same rate on either side of peak lift in equal increments (as measured by change in lift / degree).
