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?
