Holeshot Series Manifolds for 1957-’ 86 Small Block Chevrolet V8
This is a great all around street manifold. It is a direct replacement for the stock intake manifold on non-EGR engines. The manifold includes special adapter bushings to allow fitment to 1986-’ 87 cylinder heads. Also includes an adapter plate to permit use of certain square bore carburettors. Speedmaster intake manifolds are cast from steel moulds, not sand. These permanent steel moulds provide a tighter grain casting thereby reducing porosity as well as eliminating core shifting. Each manifold is 100 % pressure tested to assure no leaks.

Will also work on 1996 and later Vortec engines or engines equipped with Edelbrock E-Tec aluminum heads. As with most Speedmaster manifolds, this one features four corner water ports and is also supplied with an adapter plate to permit the use of most square bore carburettors such as the popular Holley, Demon and Edelbrock.

Holeshot Series Manifolds for 1957-’ 86 SB Chevrolet V8( EGR)
This manifold is a direct replacement for the stock 4-bbl manifold on 1972-’ 86 GM small block Chevy V8s with EGR and 1981-’ 86 GM Corporate 350 V8 engines with EGR. It is essentially the same design as the above two manifolds but incorporates EGR. Some applications may require our EGR adapter to provide clearance. This manifold is a great all around street manifold that is street legal on the listed applications. It will accept late model choke, waterneck, air conditioning, alternator, and HEI ignition systems. The manifold features dual distributor holddowns and four corner water ports. It is also supplied with an adapter plate and gasket to accept most square bore carbs.
