If I was going to get a cam for my engine, what else needs to be modified? What cam would be good for my engine (stock except for K+N filters)?

Roller rockers- how much power do they give me, and are they a mod that can be done just by itself?

I have little money and a desire for power..so I'm trying to think of little things to gradually make my IROC faster. Anyone who has done similar low-dollar minor mods- your help would be appreciated! Thanks

 

You could put on a hi-flow cat, and add a lightweight flywheel. The cat will cost you anywhere from $100-$250 depending on the quality you want. The flywheel you can get from gm for $150.
