S.U. H-8 Sandcast Carbs. An original racing option for the XK-120, XK-140 and C-Types, these excellent replicas are concours quality. They bolt to the stock manifolds and use stock linkage (the linkage that differs from stock is included). These carburetors make a great set-up for vintage racing, C-Type replicas or just a fast street car. And, they look great.
