Another strong combo in the works featuring our Iron-Hide 4500 intake.

Something a little different but we're always up for designing cool parts. Custom quadrajet spacer with a 5 degree carb angle. These adapt to a 4500 bolt pattern.

The development never stops!

Our 23 Degree 4500 Jr. Low Profile intake paired up with a new matching twin blade spacer design.

Still one of our most favourite results! 870hp from 424 cubic inches. And the car shows every bit of it!

Proud to be involved!

Another iteration of our SBC 23 Degree intake for release in 2026! This is our "Mid" height intake with an overall height of 6.2in (carb pad to China rail). This design is aimed to sit between our Jr. range and flagship tall/max effort race intakes. Plenum and runner sizes have been adjusted to suit street/strip and restricted track classes.
