Re: WTB: GMC 351 or 401 v6 Magnum intake manifold
Sorry if I wasn't clear but using the magnum intake will cause the port issues, the 305E intake will fit you ports.
IIRC the 305A only has a one barrel manifold so the 305E 2 bbl intake should wake you your V6.
BTW Some have milled the top off the magnum manifold and bolted on a 4 bbl adapter if you are planning this then the magnum manifold is the one you need.
