Re: Doing a lower intake on GM 3.1/3.4? Please check this
As I posted to Ed, I can find no warpage in either the lower
intake or the heads. Remember it is the UPPER manifold that
cracked on me. Also remember that the warping only shows up
across the 1-5 & 2-6 runners after the torquing of the lower
intake. ![]()
