Description
The Hurricane manifold for Holden 304 308 355 engines (with VN heads) is the ideal solution for those building a hi-performance high revving engine with its long tapered runners. The 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.
Suits Holden 304 308 355 engines (with VN heads)
3500-7500rpm range, ideal for a high performance engine
Cast aluminium, natural finish
Suits square bore 4 barrel carburettors and throttle bodies.
Note: thermostat boss has been machined to accept SBC water necks.
The manifolds are cast in high pressure steel dies rather than the pour-in sand moulds used by other aftermarket manifold manufacturers. This type of tooling costs 2-3 times more than conventional sand-cast patterns, but the finished product is worth the additional expense. And because the cores (which form the internal ports and water passages) are mounted in steel instead of sand during the casting process, there is no chance of any core shift, which sometimes go undetected in sand castings.
