MerCruiser 72608 GM 6269318 Aluminum Intake Manifold 454 7.4L Magnum Bravo 3

Part Number(s) Included MerCruiser 72608 / 72608T Intake Manifold (4BBL) GM / Chevy / Chevrolet 6269318 (casting number) General Application / Compatibility This was an aluminum square port intake manifold with a bronze water crossover.  This was common on 7.4L 454 Mag applications mostly up until Gen V and it appears some 502 models 1985-1997. Typically just the Bravo 3 models Ideally, you are replacing this with some intake that already has the same GM casting number, but some of the 454 mag models stock setups from the factory were peanut-port cylinder heads paired with this aluminum square-port intake manifold. Definitely an odd pairing, but I suppose MerCruiser deemed it an acceptable configuration. Other Details Freshwater Used Parts No paint on this.
