After scratching my head over this for a while I finally figured it out I think. Since I pretty much ruled out an ignition problem I pulled the fuel rail and injectors last night. I found a few little pieces of what seemed to be silicone sealer (the orange stuff) in the inlet side of a few injectors. I cleaned them out, but the real issue was that the #5 injector wouldnt "click" at all when I applied power to it. I checked all 8 and that was the only one that didnt work. This makes perfect sense since #5 was the cylinder throwing the code (P0305). I ordered a new injector from Rock Auto last night. Hopefully it will come by Friday so I can verify that was the issue all along.

We figured it out. Since the ignition system seemed to check out fine, I focused my attention to the fuel system. I had good fuel pressure to the rail so I decided to pull the injectors. All 8 of them ohmed out fine, and all the driver circuits in the harness worked fine with a noid light. I pulled all the injectors individually and put power to them using a connector from and old LS harness. With 12v to each only one didnt "click". #5 which happened to be the cylinder with the consistant miss and code. I went ahead and ordered a remanufactured injector from Rock Auto (bad idea). Got it, installed it, and got a huge plume of blue smoke out the drivers side exhaust. Turns out the "new" reman injector was stick open and gas washing the cylinder. Long story short I got a GM injector from a local dealer and $140 later she runs like a champ. No miss, no smoke and ready for its final tune and dyno run on Saturday. Ill post up some dyno numbers then. Thanks again guys for all the ideas, support and for sticking with me on this.

Thanks, I really couldnt do it without all the help. They say it takes a village to raise a child. Well I think it takes a Forum to build a Car!

Well my truck is ballsless after my swap as well and this is after a mail order tune from Frost. So since I know for a fact my motor was junkyard fodder and the injectors are equally suspect, I am going to check mine out as well. Can't get excited about twin turbos when you may have an ailing motor or system. Mine revs, but hangs for a bit
