Check out Richard’s latest video. These are good builds for your ride.

CAN YOU MAKE 100 HP PER LITER WITH A CHEAP, JUNKYARD LS? WILL A 4.8L MAKE 480 HP? WILL A 5.3L MAKE 530 HP? WILL A 6.0L MAKE 600 HP, ALL WITHOUT BOOST? IS IT HARDER FOR THE BIGGER MOTOR TO ACHIEVE THE SPECIFIC OUTPUT LEVEL? WHY IS IT EASIER FOR THE 4.8L TO REACH THE SPCIFIC OUTPUT LEVEL. WHAT STOPS THE MOTOR FROM KAKING EVEN MORE POWER? CHECK OUT THIS VIDEO WHERE I RAN THREE DIFFERENT MOTORS, EACH PRODUCING NEAR 100 HP PER LITER, WITH FULL DYNO RESULTS AND DESCRIPTIONS ON WHAT WAS DONE AND HOW TO MAKE THEM EVEN BETTER.
