Weiand Stealth™ Air Strike™ High Rise Dual Plane Small Block Chevy Intake Manifold
Weiand sets new precedent in intake manifold design for which all others will follow with their new Stealth™ Air Strike™ high rise isolated runner dual plane intake manifold for small block Chevy engines, P/N 8501. The 8501 fits 262-400 CID engines from 1957-1986 and 1987 and later engines with aluminum heads.
Using Pro-E computer design, rapid prototyping, CFD air flow design, along with a permanent mold casting process, the Stealth 8501 produces more horsepower and torque then similar intakes currently on the market. The permanent mold casting process produces a lighter and more consistent casting. The results are smoother isolated intake runners that optimize atomization of fuel, a cooler denser air, better mixing of fuel/air and better distribution of the fuel/ air to the cylinders creating more power.
Each casting is CNC machined to give an exact fit and exact port match to the heads with ports measuring 1.92” H and 1.16” W. The 8501 makes best power from 1500 to 6700 RPM’s while giving excellent hood clearance with a front height of 4.19” and a rear height of 5.27” and has a 4150 style square bore mounting flange.
