MM Sells a k member and upper and lowers for the 03-04 it will bolt into the 94, the tranny mount point will be different, D&D has the mounting kit, if you have all the electronics you need to swap it all in, your strut towers are going to be tight, and all of your current accessories will not work, other than that its going to be alot of relocating lines and rewiring. I have a guy who wants to trade my 94 for his 97cobra, he did the 03-04 motor swap, it has 99+ heads, ad a J trim vortec on it, I have yet to see or drive the car, but it sounds interesting.
