Over the next several months we’ll take you through the process of adding more power and performance to our 2007 Chevrolet Silverado 3500 Duramax V-8, giving the truck a more aggressive stance, and digging into the interior to give our hauler a more luxurious feel.
Last month we transformed the ordinary 350 motor in our 1989 Chevrolet C1500 into something special. Now, it was time to tie up a few loose ends and add a fuel system before firing it up for the first time. Follow along to see how our 383 fared on the engine dyno.
After collecting an 8.26-second eighth-mile timeslip (high 12s in the quarter), we made it over to Randall’s Performance for some dyno time. Once the rollers stopped turning at 515 hp, it was clear we needed to find another 35 hp to reach our goal. What to do…
If you missed last month’s issue, this LB7 Duramax engine (out of an ’02 Chevy 2500) spent most of its life towing studio trailers in Hollywood. The LB7 went through the usual wear and tear of being an LB7 engine, which included injectors being redone two times before 200,000 miles.
