there are SEVERAL companies that are making TODAY cams that will work in the 80in EVOs
I have one, new, bought just this past June that I'm going to put in come December when I do my build.
It's a Wood W6 cam
here's a link to their site
http://www.woodcarbs.com/cams.htmwhen you read that chart, the TW cams are for the Twin Cam engines, the 'W' designation can be used in the EVOs
look at and read the specs for the W6 ...... it's a great bolt on cam for running stock stuff. It will want higher compression than you get with stock heads. I'm putting on SE heads and using a cometic .030 head gasket to get the compression that this cam will work with. You could use even more compression than what I just mention by the various methods, different pistons, custom head work, deck height, etc..
to me, the good part is that with this cam you don't HAVE to do that. This cam will work and provide really good kick butt perf. using stock pistons with SE heads (and smaller head gasket). Also, as I said, this cam will work with stock valves, valve springs... etc
I'm running a compu-fire single fire ign. love it, rev limit set to 6K and advance set to 35
Andrews still makes cams for the EVOs
Like I said, there are several choices out there ...... the ones that I looked were for BOLT ON ..... to be used with STOCK heads, valves, valve springs, and pistons
Many of them also make HIGH LIFT cams for the EVO ..... in which case you will need to do other mods to the bike to use them ......
