We spotted Bill Alvis from Tweakin’ Perfromance and his nitrous fed LS S-10 Extreme at LS Fest East 2018. In this video, Bill gives us the low down on the S-10 and how the short-block came straight out of his very understanding wife’s GTO. Bill runs our Holley Sniper Stealth 4500 EFI on top of a Weiand Supercharger giving it boost, and also runs NOS up to a 100 shot! Check it out!
