Chevrolet - GM - V8 Small Block

Direct replacement water cooled exhaust manifold port side (left). The exhaust connection is a 2-1/2" NPT threaded end plate. This is a log style exhaust manifold used in some GM V-8 marine engine applications.

Engine application: Chevrolet V8 OHV 305, 307, 327, 350 and 400 C.I.D., 1962 and up.

Barr Marine castings have a thicker interior wall, are painted to match original manufacturer colors and are packed in foam for added protection during shipping and storage. Barr manifolds and exhaust connectors are designed to minimize back pressure, and in many cases more r.p.m.'s are achieved after replacing an OEM manifold with Barr replacement parts.

• Manifold end plate and gasket listing: front end plate 1-0032, front gasket 1-0019, exhaust end plate 1-0025, exhaust end gasket 1-0019, header adaptor 1-0001.
• 3 year limited warranty on Barr exhaust manifolds, risers and exhaust connectors (1 year when used for commercial purposes).

Water cooled center discharge manifold to fit the small block GM engine (3/4" N.P.T. cooling hose connections). All years.

Engine application: all small block Chevrolet V8 283 to 400 C.I.D.

Fits Chevrolet small block V8 283, 302, 305, 307, 327 and 350 C.I.D., all models (aluminum center riser generic).

The Barr Center Riser is a two-piece aluminum manifold/riser ideally suited for replacement use where riser protection is required. It uses flexible exhaust hose, which makes it easy to connect to existing exhaust lines, and all elbows (cast iron) can swivel inboard or outboard for a perfect fit. The manifold/riser is designed to limit back pressure on the engine, resulting in more efficient engine performance. The manifold and riser can be reversed and will fit either side of the engine. Cast of 356 T6 aluminum, well suited for fresh water marine applications.

• Includes CHV-1-92P manifold mounting package to the cylinder head (bolts and pipe plugs).
• One year warranty.
