There's just something about a freshly machined Cummins head! We just wrapped up this 6.7 Cummins cylinder head and this customer wanted all the seal and went with a HAISLEY MACHINE fire ring head gasket. Topped off with our competition valve job too! All the work was done IN HOUSE and is now ready to take all the world.

TWO of our Street Fighter Cummins long blocks finished up today. These monsters will make well over 1,000hp and run like a brand new engine. Our Street Fighter long blocks come standard with oversized MAHLE Motorsport North America pistons that are coated by our good friends at Mountain High Diesel Performance, Wagler Competition Products rods, Clevite H series bearings, ARP main studs, and all the quality machine work you'd expect from us. The cylinder head gets our tired and true port work, increasing the flow IN & OUT to over 225cfm, Inconel exhaust valves and intake valves, flame hoop grooves cut in both the block and head, and some quality ARP 625 head studs. We cant wait to see these things in action!

ATTENTION!! We have some new policy changes that took effect at the beginning of the year. If everyone can take a minute to look them over and keep them in mind. These changes needed to be made in order to keep supplying our customers with the best products and services. We look forward to the 2025 season with all our current and future customers!

Finished a balance job up today for ANOTHER Cummins build we have going on. As you can see in the first spin the crank was in tolerance, but it wasn't good enough for us. Under 1Gram in the final spin. CWT INDUSTRIES making balance jobs great again! This build is getting a set of Wagler Competition Products Street Fighter Rods and our in house port work to the cylinder head.

All you drag race big block guys, we have a block that you need! Merlin 2 block, std deck height, bore is currently 4.525, bushed for .842 lifters, and has been oring'd on the deck. Great foundation for next season. $2,900 as the block sits. But if you are interested in a short block or full engine we have the parts here to finish it out.

Been putting in some work on this 5.9 Cummins head. Flowed it once we got it cleaned and steel shot to know where we start. After our port work, valve job, and blending we gained over 60cfm on the exhaust and over 50cfm on the intake! BIG jump in air flow like this will really perk this diesel up and make an awesome street and pulling truck.
