I have been starting to do some David Vizard Research.

Can anyone help me understand the difference / similarity in these Cam terms?

LCA - Lobe Center line angle - Mr Vizard uses this term in his writing.
He describes the Lobe Centerline angle as being Narrow vs wide...
Is it the same as.. LSA - Lobe Separation Angle? as I understand that one.

Thank you!

Greg

Yes, David Vizard uses LCA when speaking of the angular displacement between the center-lines of the intake and exhaust cam lobes which is the same as LSA.
