Their work ethic and ability to bring concepts into reality has been something to behold in NHRA pits for more than 50 years.

Builds engines for: Joey Grose

Favorite accomplishment: “Being able to qualify with our own engine and our own power.”

DRCE architecture used: DRCE 3 blocks with 3 heads or DRCE 4 blocks with DRCE 2 heads

Philosophy when building engines: “We’re the guys running in the back, struggling to get in. The things we work on to be better are typically the cylinder heads and manifolds. We do everything in house because we can’t afford to buy parts from other people. Things aren’t going to build themselves, so the more you can figure out and do yourself, the less headaches you have waiting on someone else to do it.”

“I learned from Warren [Johnson] that you need to work hard, keep your head buried, and not get involved with all of the drama.”— Joey Grose

Technical capabilities that stand out: “We can do 99-percent of the work in-house. We can machine our own manifolds and do our own cylinder heads. We’ve even built some of our own rocker arms for other engines. We can machine a raw DRCE 4 block from start to finish, including lightening.”

Other engines they build: Top Sportsman, 8.90-, 9.90-, and 10.90-index engines.
