Three Phases of Power: Adding 100, 200, and 300 HP to a 350 Chevy
Starting with a recycled two-barrel 350 producing 246 hp, this dyno test walks through three distinct power phases, each built on deliberate component choices. The final combination reached 543 hp at 6,900 rpm from 355 cubic inches.
Chevy 327 vs. 5.3L LM7: A Dyno Comparison of Two Small-Block Generations
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.
