Big-Hulk 7106 Intake Manifold

Big Hulk-BBC 7106 is a 4500 Series cast aluminum intake manifold developed for 10.2 to 10.6  Deck BBC Engines utilizing a Spread Port head, operating in the 6000 to 8000 and up, RPM range.   

Big Hulk offers design features never offered in a cast single 4 manifold making it a very unique design.   This manifold design has proven in testing to offer excellent distribution in all cylinders due to the well defined runner entry.

Big-Hulk can support an 8500 Series Throttle Body along with the 2.800 Carburetor variants.

Big-Hulk is a per order casting.  It is a 'commercially available' intake, but due to the flexibilitiy I am offering in deck heights, this intake will be final machined per order.   3-4 weeks delivery time unless otherwise communicated.  Please review deck height options.

Hulk-BBC, due to it's manufacturing techniques offers a clean, and accurate runner core.  It is a 'Cast Ported' manifold offering performance right out of the box.   That said, the casting does offer architecture to develop further with larger plenum requirements, or runner design adjustments. 

Hulk-BBC does not have water cross over.  It has -12 ORB water ports machined on 4 corners.

Efforts have been made in the design to reduce weight as much as possible.   10.600 Deck is in the 33 lb range.   10.2 is around 30 lbs.
