We go from 5.3 to 383 with our no-longer-little LS engine. (http://www.superchevy.com[B)In the previous two installments of Modern Mouse, our latest Super Chevy dyno mule, we subjected the little 5.3L LS to a whole slew of aftermarket components, including ported cylinder heads, a variety of performance camshafts, and even a dose of nitrous oxide. What started out as a humble stock 5.3L producing 343 hp and 372 lb-ft of torque eventually produced 493 hp and 447 lb-ft of torque. With the giggle gas, the numbers jumped to 616 hp and 587 lb-ft, but even without the nitrous, the 5.3L was one healthy small-block.
