Big-Block Chevy 454 Top-End Upgrade: Edelbrock RPM Heads, Intake, and COMP Cam
A Gen VI 454 pulled from a wrecking yard produced 369 hp in baseline trim. After installing Edelbrock RPM 454-O aluminum heads, a Performer RPM Air Gap intake, and a COMP XR271HR12 hydraulic roller cam, output climbed to 481 hp and 527 lb-ft of torque.
LQ4 6.0L LS Build: Compression, Cam, and Ported Heads to 549 Horsepower
A stock LQ4 6.0L truck engine was upgraded with LQ9 flat-top pistons, a COMP 54-454-11 cam, Stage 2 ported 317 heads from Total Engine Airflow, and a FAST LSXR intake. The result: 549 hp at 6,700 rpm and 481 lb-ft of torque at 4,900 rpm.
Dyno Test: Trick Flow Twisted Wedge Track Heat Heads on a 331 Windsor Stroker

The factory-rated 365-hp L76 327 and the truck-duty 5.3L LM7 are separated by decades of engineering evolution but share nearly identical displacement. We ran both on the dyno in stock and modified configurations to see where the numbers actually land.
LS3 Valvespring Dyno Comparison: Measuring the Power Cost of a Spring Upgrade
Dyno testing on an LS3 crate motor showed that upgrading from stock valvesprings to Comp Cams beehive springs cost 4 hp above 5,500 rpm - a minor trade-off that enables cam upgrades worth 70-plus horsepower. A Speedmaster fabricated intake supported the high-rpm cam testing.
