what are some small things i could do to my mach to get more horsepower??
Exhaust, Intake, Manifold spacer, even though they don't add HP but u can do 4.10's. U ca do an electric water pump too. seen a few guys do that to make some extra power
Remember though. Dyno Tune wil be your best friend. try and stay away from the canned tunes.
are you talking about small parts or small things that don't cost anything?
