ok im looking 'to seam to find it but is there any gains at all from the newer 3.4l camaro top hafe of the intake vs the older 3.1L camaro intake i know there was some work done years ago on this

No not really. And it doesnt fit quite well as the 3.4L had a DIS ignition and no dizzy. So there is fabrication involved. And IIRC they dont flow much better at least not for all the work that has to be done.

Easier to stick with the 3.1 top or go hybrid.
