LS3 416ci 605hp Complete Engine Upgrades
Our 416ci LS3 is one of our best sellers for sure, making 605hp it is super powerful but still has good street manners overall. We have seen gains up to 635hp with aftermarket Trick Flow CNC ported heads and a Fast LSxR 102mm Intake. Using good performance long tube header that has 1 7/8” primary tubes and a 3.5” collector is recommend. This engine works best with a 3000 rpm stall or any manual transmission and a 3.73 gear or lower, you can check out our offerings from RPM Transmission below.
