Stock cam

I would go with the E303. There have been many articles on the cam and the basic operating rpm is 2500-5500.

I wouldn't waste my money on a cam

It may help you decide.

I forgot to mention that the F303 is too big for a stock 5.0.

IF you want to keep it low budget + keep using the stock heads, you could upgrade the valve springs, use 1.7 ratio rockers and degree/advance the stock cam 2°-4°..... then concentrate on upgrading for the restrictions on the intake. LUK

when i put the new cam in do i have to change the cam bearings or the lifters?

NO on the bearings (if no oil pressure problems were present)..... YES on the lifters, due to mileage and my own personal experience.
