Professional Products 52003 Cyclone Chrome Manifold for Small Block Chevy with Vortec Heads

Professional Products Cyclone Chrome Manifold for Small Block Chevy with Vortec Heads features a real chrome finish. This manifold can be used on any Chevy V-8 engine utilizing the late Vortec head. This manifold has provision for external water bypass. It also features four corner water outlets, dual distributor hold downs, includes a square bore carb adapter and gasket, and will work with a late model style water neck, alternator, HEI and air conditioning brackets. It will also fit 1996 and later Vortec engines with some minor modifications. The modification is not to the manifold itself. It just requires running a short section of heater hose from the pipe tapped hole in the front of the manifold to the 5/8 inch hose nipple on the passenger's side of the water pump. The 1966 and later Vortec blocks do not have a water bypass in the block and this hose takes care of that issue.
