Bigger is always better right?  Well maybe not. Or maybe so. Hmmm, is the jury out? Maybe. In todays horsepower video Richard pits a 5.3 vs a 6.0 to see which one is best stock, modified and then when equipped with a stroker kit. Will the stroked 5.3, at 383 cubic inches be as good as the 408 made from the 6.0? I can tell you that I have been around for tests of both combinations and they are impressive. I love a stroked 5.3 combo, and have made well over 1,000 horsepower with one with a little street cam and some boost. And all without doing anything that would be considered radical or too crazy for a street car. But does that make it better than the 6.0 is in this battle? Watch and see.

Here is the video description from Richard.

JUNKYARD LS COMPARISON-5.3L & 6.0L-STOCK. MOD & STROKER! HOW MUCH POWER DOES A STOCK 5.3L OR 6.0L MAKE? WHAT ABOUT WITH A FEW MODS LIKE PORTED HEADS, CAMS AND INTAKE? WHAT HAPPENS WHEN YOU STROKE AND POKE A 5.3L OUT TO 383 CUBIC INCHES? HOW ABOUT WHEN YOU DO THE SAME TO A 6.0L AND PRODUCE A 408 STROKER? HOW MUCH OF A DIFFERENCE DOES THE ADDED CUBIC INCHES REALLY MAKE? IS BIGGER REALLY THAT MUCH BETTER?
