The 5.3L LY5 that comes stock in 2005-2012 Chevy and GMC pickups may not be the biggest LS on the block, but its got plenty of potential to be among the baddest. The truth is that these mild mannered 300 horsepower iron block LS engines are just a few pounds of boost away from making LS7 type power – or even more.

Just ask our buddies at LaFontaine Performance Center. These are the same guys who make the beastly GT454 GMC Sierra, so you know they’ve got just what you need to take your 5.3L pickup to the next level. They recently just sent us over some info on a special they are running on parts and install of a Whipple W140ax twin-screw supercharger for 2005-2012 GM pickups. Check out all the info from LaFontaine below, or head over to their website for all the details!
