200 Pro CHI heads doing what they were built to do.
Hyd roller cam, custom spacer plate, and a 400/444 combo coming together one piece at a time. Progress can be slow, but this thing is shaping up to move some serious air.

What’s your 200 Pro setup looking like? Drop it below — let’s see the builds.

Thx Robert Hearrell

Limited by the rules. Unlimited by the thinking.

When you're building for a jet-limited class, every inch matters. Induction Solutions recently showcased a **Small Block Ford fitted with CHI X275 Direct Port heads and an aluminium "trash can" plenum upgrade**, designed to maximise airflow and fuel distribution in an environment where space is at a premium.

The direct-port system allows precise fuel delivery to each cylinder, while the compact aluminium plenum package keeps everything tightly packaged without sacrificing performance. It's a perfect example of what happens when smart engineering meets serious horsepower demands.

At CHI, we've always believed that power isn't just about bigger parts. It's about getting the most out of every cubic inch, every port, and every restriction you're forced to work with.

✅ CHI X275 Direct Port cylinder heads
✅ Compact aluminium "trash can" plenum upgrade
✅ Optimised for jet-limited competition classes
✅ Built when packaging space is just as critical as airflow

Sometimes the best builds aren't the easiest ones.

They're the ones that make people ask…

"How did they fit all that in there?"
