depends on wat kind of manifold you are using. for the the price stay away from the CTR cams. they are way to expensive for stock. if your going to use a log manifold use the stage 2 turbo cams. and if you have an equal length use the pro 2s. big, aggresive cams work very very well with equal length manifold and are way better than stock. just take a look at the cams i'll be using with my equal length manifold. i've done tons of research on this and there are plenty of dyno's that prove this. with log manifold it better to have a cam with high lift and short duration and with equal high lift long duration. just pick a good cam according to wat your whole set it up is going to be like.
