Don't understand cams

There is no need to be frustrated. OP expected a simple answer ("can I use this cam... will it have a lumpy idle"), and that started the , err, discussion.

Quote of the day is again YR: 'You can call 10 different cam grinders, with exactly the same specs and get exactly 10 different sets of cam specs. All THEY all wrong? Nope. It's the same thing. They all have their ways, their understanding, their ways of conceptualizing of what the correct cam timing events SHOULD be. They are not all wrong, just different.'

As easy as that.
