What Our Customers Say

Butler Performance has been trusted by Pontiac enthusiasts for over 60 years. Here's what some of our customers have to say about their experience.

"I've ordered from Butler Performance for over 15 years. They know their product better than anyone and their cam recommendations have never let me down. I've built four Pontiac engines with Butler parts and every one of them ran exactly as described. You don't find that kind of expertise and honesty anywhere else."

— Tom R., Ohio

"Butler built my 455 HO. It dyno'd at 512 hp and 535 ft-lbs of torque. The documentation they provided was incredible — every part listed, every clearance documented, and a certified dyno sheet. Best money I've ever spent on an engine. It's been in the car for three years and hasn't missed a beat."

— Mike S., Texas

"Called with a question about my 400 build and spent 45 minutes talking to an actual engine builder. He walked me through every option, explained the trade-offs, and helped me pick the right combination for my car. You just don't get that kind of service anywhere else. That conversation alone was worth more than what I paid for the parts."

— Dave M., California

"I was nervous ordering a complete crate engine online. Butler walked me through the whole process, answered every question I had (and I had a lot), and the engine arrived in a custom crate with a full dyno sheet. Installation was straightforward with the documentation they provided. The engine started on the first crank and made the power they promised."

— Chris W., Florida

"Butler's cam recommendation saved my build. I had a cam spec'd by someone else that would have been a disaster for my street car. One call to Butler and they talked me through exactly why it wouldn't work and what would. They were right. The engine is a completely different animal than I expected — in the best way."

— Kevin H., Pennsylvania

"Ordered parts for my '70 GTO 400 build. Everything arrived correctly, quickly, and exactly as described. One part had a minor shipping damage issue and Butler handled it immediately, no questions asked. That's the kind of customer service that keeps me coming back."

— James L., Michigan
