3-4 weeks to ship. Hulk-BBC 5598-R is a high rpm 9.8 Deck manifold option. Shorter runners, and plenum maximized. My intake manufacturing process allows me to have variants within my Hulk BBC Casting, to suit combinations that fall beyond the parameters of my traditional casting. This saves hours of port work and $$. I offer this variant for an additional 200.00 which is significantly cheaper than muscling a grinder for 10 to 20 hours. This design is self explanitory. Straight line of sight. Optimized runner length for 9000+ rpm. Large open plenum. There's no voodoo in this design to ponder. Just straight forward, plenum and runners falling just short of a tunnel ram design. Due to the plenum design, this has 1/4-20 carburetor fasteners. Step washers can be purchased from McMaster to positively locate the carburetor. This is a common condition when you want all the plenum you can get.
