An AN 002 cam makes peak power approximately between 5500 and 6500 rpms in a blueprinted Animal.
Advancing it will give you more power on the lower end of the spectrum.
Taking out some valve lash will also reduce the duration and max lift.
It's an off the shelf cam that may give you what you want.
It is obviously illegal to use in a LO 206 and I would never recommend or condone cheating but if you are just playing around in your back yard have at it.
Gee, I don't come here everyday. There's a track were you pay anytime you want to run and during the week I'm the only guy there. Anyway I'm dumb for asking lo206 guy about engine mods so done with this.
Well excuse meeeeee. It seems to me that since I took the time to look up the data for you that you would have the courtesy to answer. Im sorry I won't bother you with an answer in the future.
