I have a 350, headers, holley edelbrock intake, flowmaster exhaust (no smog pump or cat). What else can i do for easy HP? I want to make a ram air for my air filter...anyone have instructions. I can't remember the Hot rod or super chevy the instructions were in. I don't want to blow 2000 on a supercharger (and 3 grand to install), or bore it to a 383 so it can glow like a lantern. I just want some more kick.
Thanks

I'd say (though not exactly easy) its time for heads and a cam (which i myself need badly but lack $$ right now)

 

NOS...or as some ricers call it noss. Just make sure you engine can hold it though...
