Just because the LS engine has been so popular the past several years, doesn’t mean that other engines are irrelevant, and I often refer to a Big Block Chevrolet as a “man motor” for a reason. They make big power, big grunt, and are still BY FAR the most popular engine platform for racing. Period. They also happen to be a great engine for towing, when properly setup, and they came in a jillion trucks over the years. I happen to own a big block powered square body dually and have been debating what to do to make the 454 under the hood even more capable while pulling a big trailer down the highway. Should I go for a turbo combo? A blower? More inches? We shall see.
But what if you want to make cheap power for your hot rod? This video is all about DIY horsepower using the big block you already have, and I love Richard for it. Watch, learn, and tell us what you think.
HOW DO I MAKE CHEAP, JUNKYARD BIG BLOCK CHEVY POWER? THE ANSWER IS EASY, JUST ADD NOS OR BOOST! NOTHING BEATS THE JUNKYARD FOR AFFORDABLE, PERFORMANCE MOTORS. CHECK OUT THE TESTING ON THIS GEN 6, 454 BBC. TO ILLUSTRATE HOW EASY IT IS TO ADD BIG POWER, I FIRST COMPARED THE FACTORY EFI INDUCTION TO A SIMPLE CARBURETOR AND DUAL PLANE. THEN, I APPLIED A LOWBUCK (HOLLEY SNIPER) PLATE NITROUS SYSTEM. THEN AFTER ADDING A CAM AND SPRINGS (TYPICAL UPGRADE), I SHOWED HOW EASY AND EFFECTIVE IT IS TO ADD BOOST FROM A TURBO(S). WITH RING GAP, THIS TURBO 454 EASILY EXCEEDED 800 HP! WHAT WOULD YOU DO WITH 800 HP AND OVER 800 LB-FT OF TORQUE?
