OUR ORIGINS
Building engines since 1976.
GCH Long Block Racing began rebuilding hot rod engines in the 1970s. Now we’re on the cutting edge of Subaru’s ever-improving, ever-evolving performance technology.
We are a second and third generation machine shop with a combined total of 65 years of experience. We’re proud to offer top-quality engineering technology. Every job that comes through our shop is custom-built to order.
Fully in-house, we have control over what leaves our shop. Each block and head is tested through our rigorous inspection from start to finish by our team of state-certified machinists. We measure our blocks inside and out to ensure the best tolerance levels and specs.
Every job is custom-built
to order.

WHAT PEOPLE ARE SAYING
"Bought several engines from GCH near the end of last year with great success. Engines came in a timely manner and went together without any hitch. No messed up threads or surfaces on the blocks like we have encountered with other engine rebuilders in the past. Communication was great and we will be doing much more business with them in the future."
