B303= at .050" lift, int. 224 deg, exh. 234 deg. .I/E .480 lift.
X303= at .050" lift, int. 224 deg, exh. 234 deg, I/E lift is .542 the lift is the big difference. Charlie is right B303 will be a better cam for the street.
: I'm planning on buying a crate motor, and have a couple of options that I need advice on. I plan on using the car strictly for street, so I am going for reliability. I have an option of Motorsport b303 or x303 cam. Which cam would be best for street? Is either cam TOO MUCH cam for a reliable daily driver? I also have the option to upgrade from stock stamped rockers to either 1.6 or 1.7 roller rockers. I understand the benefits of roller rockers, but which ratio would be best? Any help is greatly appreciated.
