What camshaft should I get? 97 5.7L
 

I have my engine torn apart and now im wondering if I should replace my camshaft with something better to get more performance.

I have the MFI not TBI and some of the camshafts I see reccomend or require a certain intake manifold but those are only for TBI setups.

So is there a camshaft I can get and what else would I need or need to know?
