The GM Outlet - LS3 power hack! Check out Richard Holdener...

Gen 2 LT1 Mods! Every day on the dyno is a good day! Especially when you add ported heads and a @tpi_specialties ZZ409 cam up in here! Check@out the power gains offered by the upgrades! Full vid is up ! | Richard Holdener

LS Fest West gunna have a few extra cylinders when I arrive! Long haul down from Seattle to Vegas Baby! V12 Rollin’ out! Stop by and see me. | Richard Holdener

What happens when someone sends me an adjustable LS intake all chock full of Carbon-Fibery Goodness! I test it! Since the @performancedesign Carbon pTR was adjustable, I ran the different stack lengths (so cool)! Good thing the L33 had a BIG @briantooleyracing cam on ported @trickflowspecialties 220 heads (further ported by BTR). Check out the results in the latest vid! Who would want this thing under their hood? | Richard Holdener

Did you know CEL actually stands for Cam Engine Light! When life gives you a Check Engine Light (CEL), It’s time to get a cam! Add 60-75 Hp to your LS for just $179 shipped. The Low Buck Truck works with stock converters and cheap 550 lift springs! The bigger Truck Plus adds power above 5000 rpm and needs .600 lift springs. Shoot me an email to order before the price goes up! I also have some 3X #wrongcam shirts left in red or blue! | Richard Holdener

Attn: Internet Engine Experts! What do we need to change on the 476-HP 4.8L to reach 500 HP? Check out the video where I covered what we used on the SBE (junkyard) LR4 4.8L to reach 476 hp, but let me know in the comments what we need to make 500 HP! Let’s hear those ideas! Full vid is up with my ideas! School me! | Richard Holdener
