Trust us if your going to put a 10.25 piston in then you'll really appreciate a better then stock cam. Jasons .390 Web cam is a pretty good grind.
 
I'll tell you guy's something that really suprised me about Web...
I used this computer program to actually help me pick the right cam for what I was going to be doing or riding. Will I thought for sure the Megacycle Mid-Range 252-x2 would be the one that would be it or have the most all around average power.. Well to my suprise the Web .390" had the most average HP and TQ across the RPM band. No it doesn't make the most peak power but it has a very broad curve. Where the others have a smaller curve but make more power right at that RPM. So the bike would be harder to ride fast.
Just remember that the stock cam is only .341" lift and 233 duration @ .040" of lift. So really small.
 
the prices should be posted right by the grind number on the cam, i suggest calling them, they are very friendly and have great service, just putting a little plug in for them since i just got my cam and springs through them and their service was excellent!
