The real proof is in the results, at SDX, with three wins, and 1 runner up to a Duramax. It’s a fact that the top Cummins pulling engines were out of Haisley Machine. My interest is that all 4 had ZZ Custom Fabrications manifolds and cylinder head programs proprietary to Haisley.
It wasn’t about Bling or eye candy, but about extensive R&D and hard work. Congratulations Haisley Machine, and ZZ custom Fabrication. Job well done
