WEIAND X CELARATOR 351 4V CLEVELAND SINGLE PLANE PERFORMANCE MANIFOLD
PROFESSIONALY PORT MATCHED to suit STOCK 4V HEADS ,..the intake gaskets are still intact to show the perfect port matching carried out to suit a stock 4v intake port .........
in great condition ,...save hundreds of $$ on a new manifold,..not to mention the time or money required to open up the ports.
for some reason the later Weiand 4v manifolds require a lot of work to port match perfectly to a 4v head.... [ you would think they were a 2v manifold by looking at the ports ]
port matching is a must !!,....it increases air speed and improves efficiency ,........with this manifold all the work has been done for you.
good luck.
