Proflow’s single-plane Max Jr intake manifolds are very versatile and can be used for both drag racing and street applications. This manifold design features extended tapered runners and smaller plenum chambers tuned for maximum performance between 3000 to 7500 RPM. They have provision for nitrous bosses to be tapped and are available in Silver and black powder coated cast aluminium finishes.

Note: Must use SB Chev thermostat housing. 

Note: For VS series 2 & VT roller blocks, you must remove the original lifter cradle and replace with a tie bar lifter system (CROW-5208HR) to fit this manifold.
