In this episode of Project LS Next, we find out what Mike Mavrigian’s 440 cubic-inch LS engine made on the dyno—after he installed the induction system, ignition, and a pair of valve covers. Don’t cheat and scroll to the end of the story—that’s not cricket. [portfolio_slideshow id=64153] Induction System We opted to go with a carbureted
Editor’s Note: We’re back with Part Two of Project LS Next, a 440 cubic inch LS engine based on Dart’s LS Next iron block and built by Mike Mavrigian at Birchwood Automotive. In Part One, we covered the block prep, the rotating assembly, and camshaft installation. This round is devoted to the oiling systems, valvetrain,
Editor’s Note: Mike Mavrigian of Birchwood Automotive is back with another cool engine build. This one is a 440 cubic inch LS engine based on Dart’s LS Next iron block.

But not just any LS motor. The guys at Chevy Hardcore were looking to build something that could tear up the track during the day and get you
[portfolio_slideshow id=22157] As the guys at Chevy Hardcore point out, 500-horsepower ain’t what it used to be. A 500 horsepower daily-driven street mill simply won’t garner attention at local meets or gas station pumps like it used to.
