Engine Power now has it's own YouTube Channel! We are still part of the PowerNation family, but all our engine content will now be posted on this channel. Engine building, machining and assembly, and engine testing all in one place.

Video Description

We're putting the finishing touches on our beastly 427 cubic inch LS street power plant! We give it a classic Chevy orange paint job, outfit it with swap-ready accessories, and install a trick EFI system for bulletproof street performance. Watch as we install a big gun hydraulic roller cam, Trick Flow Gen X 280 cylinder heads, and the user-friendly Fitech Ultimate LS injection system. Then, we hit the dyno to unleash its impressive horsepower and torque, proving this pump-gas friendly LS engine is ready for anything you throw at it, including boosted applications!
