Holden V8 253-308 Dual-Plane Intake Manifold, Street

This is a great all round street manifold. It is a direct replacement for the stock intake manifold on Holden Red/Blue/Black 253-308 engines. Includes a Spacer plate to permit use of certain square bore carburettors. These 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.

Replaces Edelbrock ED2194

• Suits Holden 253-308 V8 (Red/Blue/Black)

• Does not have a provision for external heat crossover.
• Idle-5500rpm range, ideal for a street performance engine

Note: Will not suit Holden VN EFI Heads. 

These 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.
