JUNKYARD BBC BATTLE-GEN 6 7.4L 454 VS GEN 7 8.1L 496. WHO IS THE LOW-BUCK KING OF BIG BLOCK TORQUE?

HOW MUCH POWER DOES A CHEAP, LOW-BUCK, JUNKYARD 454 MAKE? HOW MUCH POWER DOES A CHEAP, LOW-BUCK, JUNKYARD 8.1L MAKE? DOES AN 8.1L MAKE MORE LOW-SPEED TORQUE THAN A 7.4L? CAN THE 454 MAKE AS MUCH POWER AS THE 496? HOW MUCH POWER IS A CAM SWAP WORTH ON A 7.4L? WHICH JUNKYARD BIG BLOCK SHOULD I CHOOSE FOR TOWING? CHECK OUT THIS VEIDEO WHERE I COMPARED THE POWER AND TORQUE OUTPUTS OF TWO JUNKYARD BIG BLOCKS-THE GEN-6 7.4L 454 AND THE GEN-7 8.1L 496. I EVEN MODIFIED THE SMALLER 454 TO EQUAL THE POWER OUTPUT OF THE 8.1L, BUT IT STILL DID NOT MAKE AS MUCH LOW-SPEED TORQUE!
