This is and will always be a debate, because ...
The came manufacturers do not give you the specs of the cam your buying ( if you want buy a came for a small block Chevy from say Crane cams or say Lunati cams they will openly give you the specs to there cams and witch cam will give you more power where in the powerband ) unlike company's that make cams for minis as far as we know they are all just a copy of another .
Now that being said yes they do give you more power and are a must for anyone wanting more power out of your mini,
Has anyone on the speced a cam ?
I know that takagawa makes different cams for the +R head but they are the only ones.
Witch is a lil crazy considreing how many different cams there are for a chevy v8 .
It would be nice to know witch cam makes better lowend and witch makes better top .
When building a V8 cam is the most important thing next to oil in the motor ,you can have the best cyl head in the world but if the cam is not holding the valves open long enough to get the air in there it is point less.
Sorry for the rant guys this just always wondered why .
