23 Degree Intake GM# 10185063
This manifold is used on all ZZ series 350 HO engines and also can be used on all small-block Chevrolet's thru 1986. This aluminum manifold produces the same horsepower as the previous high-rise design, but provides increased hood clearance and more versatility. It has a dual-pattern flange that can accommodate both standard-flange Holley and spread-bore Quadrajet four-barrel carburetors. This manifold has provisions for all late-model accessory brackets, EGR (exhaust gas recirculation), and an integral hot air choke. A heat shield can be mounted underneath the manifold to prevent coking when EGR is used. Technical Notes: This manifold carburetor flange is approximately 1/2" lower than the LT1 manifold.
