I personally love this swap and can't wait to see the final product.
As for Doug's aesthetic concern, I have often thought that the coil packs do take a little away from the look of the engine. Interestingly, I have seen remote mounts for the coil packs on the LS3 but do not know if they make them for the LS7. I have heard mixed reviews on these. There is also a company making a cover that looks like old school big block valve covers to hide them on the LS3.
I still would like to have that old, junk, worn out LS3 they are replacing for my Pantera.
Keep up the good work Chris and Scott.
