newbie question on cam

[mud4evr]

I have a bone stock 2008 400 ex. If I drop in a stage 1 hotcam will there be any noticeable difference. Thanks for any feedback

[PaRedneckRiders]

yes, it should have more bottom end power.
But if u plan on keeping stock bore/comp/stroke I would get a sparks +6 timing key

Or both of them, the sparks key is relatively cheap and ive heard good results, i run a +3 because of the high comp piston and 88mil bore (426)

Can you tell me more about this sparks key Thanks

[PaRedneckRiders]

it advances the timing 6 degrees and really wakes a stock motor up.

im not sure of all the technical info
Here is a link to the key from sparks
