CAN A CHEAP, JUNKYARD 4.8L MAKE 500 HP WITHOUT BOOST OR NITROUS? HOW TO MAKE A 500HP (ALL MOTOR) 4.8L! WHAT MODS DOES THE 4.8L NEED TO MAKE MORE THAN 500 HP? BOOST IS EASY, HOW DO YOU DO IT WITH NO BOOST OR NITROUS? HELP ME DECIDE WHAT TO CHANGE ON THE 476HP 4.8L COMBO TO INCREASE THE POWER OUTPUT UP TO 500 HP. DOES IT NEED MORE HEAD FLOW?? DOES IT NEED A BIGGER CAM? DOES IT NEED MORE COMPRESSION? DOES IT NEED A DIFFERENT INTAKE? DO THINGS LIKE HEADERS, LIFTERS OR OILING SYSTEM MODS ADD POWER? HELP ME CHOOSE WHAT MODS ARE NEEDED TO PUSH THE 4.8L UP TO 500 HP. (go to richardholdenerperformance.com)
