CAN I MAKE MORE THAN 500 HP WITH AN ALLMOTOR 5.3L? WILL HEADS, CAM AND INTAKE (HCI) MAKE 500 HP? IS AN L33 A GOOD MOTOR? HOW MUCH POWER CAN A JUNKYARD 5.3L MAKE? HOW WELL DO TFS 220 HEADS WORK? WHAT IS THE BEST CAM TO MAKE 500 HP? WHAT INTAKE SHOULD I RUN? SHOULD I RUN FLATTOP PISTONS? CAN I MILL MY HEADS? CHECK OUT THIS VIDEO WHERE I TOOK A HIGHMILEAGE, JUNKYARD L33 (ALUMINUM) 5.3L AND TURNED IT INTO AN ALLMOTOR TERROR! AFTER MAKING 480 HP WITH A BTR CAM AND FAST INTAKE, I DECIDED IT WAS TIME TO TOP THE 500HP MARK! I THEN ADDED THE NECESSARY HEAD FLOW AND A MODIFIED INTAKE TO PUSH THE POWER BEYOND THE 500HP MARK.
