You should be able to find some push on weather stripping that will simply push on to the shroud edge and fill the gap. As for you rough idle problem if cleaning the injectors does not work I think run time will be the main issue you will find. All of these EFI motors need several start cycles and run time to self tune. As for the hot and cold header tubes is it possible that may have something to do with this being a D.O.D. motor? Looking forward to getting started on my 2005 5.3L swap for LowBuck here soon. I have the motor and 4L60 sitting on the shop floor with 20K on the ticker as well as the harness and computer from Street and Performance ready to go. I am going to order the ECE mounts from Stan today or Monday then I just need the time. And for those who asked yes stock Camaro manifolds will fit really well in the truck frame. I will go to headers some day but I am un-decided if I want to go with a Turbo set up or charger so until I figure that out I will run the manifolds.

Thanks for the input. It is always good to hear someone else perspective. It is hard to think of everything when you are so focused on other parts of the build.
