I'm just clarifying some cam terminology here and need your input...
I'm again trying to picture some things in my head before putting it in motion...
If a cam has a 4º advance ground into it... does that mean it would reach its lca 4 crankº sooner than it would if it was zeroed/ "Straight-up"?
For instance my cam card states the cam is ground with intake LCA of 108º ATDC, and exhaust LCA of 116º BTDC.
Is that showing 4 "crank" degree advance in it? Would that then give 2º of "cam" degrees too?
So if it was "straight up" would it then give me an intake LCA of 112º ATDC and exhaust LCA of 112º BTDC too?
