So, you’ve got yourself a full race junkyard 5.3 and you make it into a 7,700 rpm screamer. What intake do you choose for it? I mean clearly the stock truck intake isn’t the right choice, but if you decide you are going to roll with a Holley intake, do you go High Ram or Low Ram? Which one makes the most power? Without the dyno, it’s all just speculation, and that means it is time for another dyno video from Richard Holdener.
Here it is, with numbers. Which one do you think is the winner?
Video Description:
WHAT IS THE BEST LS INTAKE? WHAT LS INTAKE MAKES THE MOST POWER? HOW MUCH POWER DOES THE HOLLEY HI RAM INTAKE MAKE? HOW MUCH POWER DOES THE HOLLEY LOW RAM INTAKE MAKE? WHICH INTAKE MAKES MORE POWER, THE HI RAM OR THE LOW RAM? HOW MUCH DOES RUNNER LENGTH MATTER ON AN INTAKE? SHOULD I RUN A SHORT-RUNNER INTAKE ON MY JUNKYARD LS MOTOR? CHECK OUT THIS VIDEO WHERE I COMPARED THE LONG(ER) RUNNER HOLLEY HI RAM TO THE SHORT(ER) RUNNER LOW RAM ON A MODIFIED JUNKYAD L33 5.3L. EQUIPPED WITH A BTR STAGE 4 LS3 CAM AND PORTED TFS 220 HEADS, THE 5.3L MADE PEAK POWER UP AT 7500 RPM, MAKING IT PERFECT FOR THIS INTAKE SHOOTOUT!
