Yes you need an 03 thru 05 cam. Most use the 03 and buy them new. Mine was around a $100.00 here on Thumper Talk OEM. Have you priced them yet?

Yes, I can get a hot cam off ebay for around $130 dollars and thats the cheapest I have found...If I can find a cam that has few hours on it for half the price or less that would be great.I dont mind getting a new cam but Im the type that tries to save every penny. Would it make a diffrence if I installed the intake cam from the 450 as well????

Most of us who use the OEM cam only change the exhaust cam. The intake doesn't seem to have any performance improvements. Some of those who use the Hot Cams replace both the exhaust and intake. The state noticeable power increases when doing that. Right now my 00 has more power than I can use effectively LOL.

The OEM YZ450 cam (5TA-12180-00-00) is currently $107 brand new at TT OEM.

Understand that it requires special timing techniques to be used in the 426 head. IMO, the OEM cam works out better fro most guys than the Hot Cams, especially than the HC E-cam by itself.
