Livernois Motorsports Heads and Cams On A Stock Modular Engine - Top Shelf Shuffle

Comp Cams Stage 4 sticks replaced the stock units.

Livernois sells billet inserts designed to lockout the VCT.

Here is one of the reservoirs that fills up with oil in order to retard the cam timing.

The Livernois insert prevents the internals from moving, effectively locking out the VCT. You must modify the tune in the computer in order to compensate for the lack of VCT.

Use Loctite on the bolts when reattaching the sprocket cover.

The engine is almost ready to be retested with the Comp cams and the Livernois ported heads. Just as this engine was being prepped, a new set of Livernois valve covers showed up from the powdercoater. Naturally we took a set of out of inventory and replaced the stock ones.

We were ready to dyno as the Kooks headers and EGT sensors were attached. The new heads and camshafts picked up 138 hp and 87 lb-ft of torque. Total output was 451 hp and 401 lb-ft-enough to propel a daily driver into the low 12s with a set of sticky tires, big gears, and a great driver.
