That’s 454 vs 496 for all of you cubic inch fans out there. Yes, there is 42 cubic inches more Big Block in the 8.1 but are it’s weird LS style enhancements enough to be the best big block ever? Thanks to Richard Holdener’s video, we’ll know in a few minutes.
Video Description:
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!
