Our Gen 3 HEMI's have been rewriting small-tire rulebooks for over a decade.
Year after year, we’ve pushed the Gen 3 HEMI harder and farther than anyone else in small-tire drag racing. Our race engine program has led the Gen 3 HEMI market forward, stacking wins and records at the most prestigious and cut-throat levels of class racing.
If you’re running – or planning to run – a Gen 3 HEMI in LDR, Pro275, X275, NT, Ultra Street, Limited 235, Grudge, No Prep or similar classes and you want a proven, front-running engine combination instead of another “test piece,” this is where your program needs to start.
Built From Real Race Data, Not Theory
Every one of our race engines is built from a proprietary combination developed in our own competition cars. We don’t guess – we test, break, improve, and repeat until it wins.
We offer multiple standard and tall deck block options to hit your specific goals:
- Cast water blocks – for combinations that still need cooling system support
- Cast solid blocks – for more aggressive, competition-focused builds
- Billet solid blocks – for maximum power and durability at the sharpest edge of class racing
Combined with the best cylinder heads for your engine's power levels and valve train needs:
- Aftermarket Cast AL Heads – for many competition-focused builds.
- Billet Solid Race Heads – for maximum power and durability.
Each engine configuration is expertly designed, heavily tested, and continually refined through constant competition use, not just dyno pulls.
100% Ready-to-Run Race Engine
Our engines are typically sold as complete, sealed packages so you get a fully integrated system, not a mix-and-match of parts:
- Custom billet intake (where applicable)
- Complete long block
- Jesel or T&D Rockers
- Solid Lifters
- Billet Valve covers
- Custom Aluminum oil pan
- Twin Screw or Gear-driven supercharger (where applicable)
- Sensors and provisions for your data system
You connect your oil lines, fuel lines, plug in your sensors, and go. No guessing, no “let’s see if this works.”

Centrifugal or Twin Screw Supercharged Package (As Priced)
Our Gen 3 HEMI + Whipple Twin Screw and ProCharger centrifugal combinations are currently the most dominant Gen 3 HEMI powerplant in small-tire drag racing, holding multiple records across small-tire classes and is rapidly becoming the go-to choice for serious Gen 3 programs worldwide.
There are numerous Gen 3 HEMI small-tire cars running this platform around the world right now, proving the combo every weekend.
If your target is a blown Gen 3 HEMI at the front of the field, this is a package we recommend.
