We built a 460 engine normally 460hp 5600rpms and 520tq at 4400rpm with Chinese aluminum heads. This engine has 9 to 1 compression. Custom designed hyd roller camshaft, Stealth intake manifold, Quickfuel carb and MSD ignition. We switched to the super street heads and used a performer intake manifold. We made 464hp at 4900 rpms and 564tq at 3900rpms. So we gained a lot of torque but we also moved the power band down 500rpms. This would be even greater if we optimized the camshaft for the heads.
100% American made
Small port size makes extremely high velocity
98cc revised chambers for possible lower compression engines
Intake port volume 240cc Exhaust port volume 87
High efficiency heads makes more power then you average street head
Replaces standard small port heads with new technology
Uses Eliminator Products special high nickel iron recipe
Uses small 2.08 1.65 valves (bigger valves available)
Uses small standard size intake manifolds and exhaust
Can produce extremely high torque at low rpms when using the right cam
Work well for hot street engines, boats, tow trucks where rpms under 5000 are really the main concern.
These heads prove to produce more hp and torque then any other production head below 4000rpms
Stock valve angles and valve spacing
As shipped comes for bolt down pedestals like D3VE type heads
(can upgrade to screw in studs and guide plates)
