This is one of those questions that EVERYONE asks when it comes to the LS engine, and the truth is that it is a valid question. If the engine platform were different, that might not be a very appropriate comparison because the price for each of those components could be drastically different. But in the case of the LS they might be a bit closer than you might think, and that only makes the decision on which one to go with, that much harder.
So watch this video from Richard Holdener to see what his dyno testing says is the right choice to make first!
Video Description:
FULL DYNO RESULTS. HOW MUCH POWER IS A CAM SWAP WORTH? HOW MUCH POWER ARE PORTED HEADS WORTH ON AN LS? SHOULD I UPGRADE MY INTAKE MANIFOLD? WHAT HAPPENS IF I UPGRADE ALL THREE? WHICH ONE IS WORTH THE MOST POWER? CAN I REALLY ADD 175 HP WITH A CAM? ARE PORTED HEADS WORTH 90+ HP? WHAT IS THE BEST INTAKE FOR MY LS? CHECK OUT THIS VIDEO WHERE I DEMONSTRATED JUST HOW MICH A CAM SWAP CAN BE WORTH (ACTUALLY MULTIPLE CAMS) ON A 408 LS! I ALSO SHOWED HOW MUCH MAST HEADS CAN BE WORTH ON A 415 LS STROKER. THE FINAL TEST OF THE TRIO WAS TO SHOW THE MERITS OF A FAST LSXR INTAKE ON A 6.0L LS? WHICH ONE WOULD YOU CHOOSE OR WOULD YOU CHOOSE ALL OF THEM?
