[3.4 grape of wrath]

I lost another engine at e-town back in Oct. The single bolt that holds the camshaft sprocket to the camshaft came loose and the valves mated with the pistons. After installing a new/used engine, I decided to do a true twin scroll turbo set up. Also did a parallel fuel system, since I have two sets of fuel rails.The last fuel injector in the system was about 6ft away from the first. Next upgrade will be a 12 bolt.
