Welcome to JCM Motors!

This channel is about real-world performance engine work, testing, and making horsepower. Follow along as engines and cylinder heads come through the shop for machining, porting, flow bench testing, engine assembly, first startups, dyno testing, tuning, troubleshooting, and more.

If you're into engine building, cylinder heads, machining, dyno testing, tuning, or just making horsepower, subscribe and follow along.

Need work done? JCM Motors LLC is a working shop and I take outside jobs — cylinder head machining, cylinder head porting, valve jobs, spring testing, flow bench work, and dyno testing. Email me and tell me what you’ve got.
