Edelbrock water neck adapter (PN 8028) is made for 1986-and-later big-block Chevy engines when installing Edelbrock intake manifolds such as #2161 or #3761. The adapter provides the correct waterneck alignment for those intake installations and is manufactured from A356-T6 aluminum for corrosion resistance and strength appropriate to coolant plumbing applications.
