Speedmaster takes on Nick Cannon’s Chevelle Project
Speedmaster takes on suppling Nick Cannon’s 1967 Chevelle with a Blown 496 cubic inch Big Block, equipped with an 871 supercharger. The engine was built and dyno tested in Rialto by the in-house assembly engineers. For optimum performance, it features forged 4340 internals and produces 750 horsepower reliably as a turnkey motor.
Speedmaster Sponsors The Engine Masters Challenge
The Engine Masters Challenge is the purest interpretation of motorsport, a sport literally made out of motors. This is the event where top builders nationwide compete for best overall power on the engine dynos at the University of Northwestern Ohio’s Applied Technologies College.
Four Dyno-Proven Ways to Add More Power to Your Mild Big-Block Chevy
A recent trip to the local Pick Your Part wrecking yard revealed row after row of what we like to call possibilities. Under the hood of each and every vehicle in the yard were the makings of a high-performance race engine just begging for a new lease on life. Of course, some would take considerable work to get there while others may never make it. But choose wisely and the rewards can be impressive. When you go looking for power in the yard, it is always best to go big, as in big-block Chevy. In the sea of stock, junkyard engines, bigger certainly means better. Since we planned on running a trio of power-adders on our junkyard “race” engine, we went right for a engine we knew was capable of withstanding both boost and juice. Though earlier Mark IV and Gen V engines are usually available, we zeroed in on the latest and greatest: a Gen VI 454 (7.4L) offered by GM from 1996-’99 (actually into early 2000).
