I noticed a couple of things right off the bat that were new to me as I’ve got zero experience working with the new LS-series engines. One, everything is metric, which required me to dust off those metric tools that I stashed away many years ago. The second was the low yield when it came to torque ratios on a number of the components, including the intake. Chevy Performance recommends an initial pass using 44 lb-ins on all the fasteners, followed by a pass of 89 lb-ins. Note that’s inch-pounds and NOT foot-pounds.
