No Springs Cam upgrade
I'm hoping to find advice on cams that don't require spring upgrades. 04 GT N/A mildly modified. Looking for that old school muscle rough idle sound, as well as the moderate power gain that comes with any cam upgrade. Also, would a TB and plenum upgrade have any effect? Currently running stock TB/plenum with intentions to purchase upgrades tomorrow.
