I was told by many of my colleagues that this cam would be great for a stock EVO. I have a light custom rigid frame so if u were to put it in a heavy bike you might not get what yer looking for. Been running the stock springs and adjustable aluminum pushrods for over 2 months issue free. I used to run the EV3 by Andrews and am very pleased wit this cam. The cam came in a standard cam box wit a instructions manual from Andrews. If you know what yer doing the came takes no more than an hour to install. Took more time adjusting my pushrods on TDC of the compression stroke of each cylinder. Great buy.
