Nothing like a little 416 LS making 733 horsepower with all motor.

These Frankenstein Engine Dynamics LLC heads are no joke!

They say green engines are unlucky… but don’t tell that to this customer! 🍀🏁

This fresh powerplant is proof that a little green can mean a lot of speed. Built with a set of AFR enforcer heads and paired with an AFR Stage 2 camshaft, this combination is designed to deliver impressive performance, and plenty of horsepower.

Precision matters.

Another day, another batch of lifter bores honed on our CNC lifter hone, and the results speak for themselves. We’re consistently hitting incredibly tight tolerances and producing finishes that ensure proper lifter fit, oil control, and long-term durability.

When it comes to engine machining, accuracy isn’t a luxury—it’s a necessity. That’s why we’ve invested in equipment and processes that deliver repeatable, measurable results every time.

If you’re building serious horsepower and want your engine components machined right the first time, we’ve got you covered.
