Project Overview

This Chevelle SS came to KTR already well put together by East Coast Cobras, running a GM Performance LS3 crate engine paired to a 5-speed manual. Solid as it was, the owner wanted more out of the platform. We answered with a Magnuson Heartbeat supercharger package, Wegner accessory drive, and Lingenfelter cam/valvetrain upgrades—a setup that wakes up the LS3 without losing street manners.

Engine & Powertrain

Starting from the 421 whp baseline, we installed a Magnuson Heartbeat supercharger for efficient boost delivery and paired it with a Wegner Automotive accessory drive kit for reliability. The camshaft and valvetrain were upgraded with Lingenfelter Performance components, completing a top-end package designed to add both power and durability.
