This is a terrific all round high performance street manifold. It is a direct replacement for the stock intake manifold on Holden V8 engines fitted with VN cylinder heads. This is an air gap style design which provides air space under the plenum which helps cool the intake charge and produce more power. Calflow 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 V8 fitted with VN cylinder heads
  • 1500-6500rpm range, ideal for a performance street engine
  • Cast aluminium, black finish
  • Suits square bore 4 barrel carburetors and throttle bodies

Note: Will not suit early Holden V8 cylinder heads. See part number CAL-76-2194BK.

Calflow manifolds are cast in high pressure steel dies rather than the pour-in sand molds 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.
