Does any company offer a Honda 300 ex camshaft for a mildly modifed engine, full pipe, re-jet and air filter that does not require the removal of stock valve springs....Just a simple drop in cam..Any information would be great..Also the airbox has been opened up as well....

 

Any time u put in a more aggresive cam u need to change the valve springs.

 

A 250X cam is a little higher performance than a 300ex cam, and will drop in, no changes needed.

 

If I drop in the 250x cam, will I notice the performance increase with the mods that I have.....I looked at Whitebrothers cams, webcams and both require different valve springs and hardened rocker arms..........Any other ideas from anyone else on their thoughts....

 

i thought with the webcam hotcam deal, you didn't need to change the valve springs.. but it is always a good idea to do with the higher degreed lobes ..

 

I went to the powerroll web page and they offer a direct drop in cam for the 300 ex....Just wonder if I will notice any power increase. They also offer another setup that requires changing valve springs as well.......Does anyone know how good these cams are....Wish hotcams offered a cam for the 300 ex. Not until next year they say...

 

you should always change the valve springs when doing a cam swap. piston to valve contact is never fun or cheap!!
