"I’ve known Ron at Dynamic for pretty much my whole life. He is a wizard with boats. The only problem I have ever had is getting my boat in there to get worked on. When a place is as reliable as Dynamic, people flock to it. If your “buddy who is a mechanic” can’t get the job done, take it here. You won’t regret it."

"Ron and Mike built 2 high performance engines for me over the years, great performance and long life for both."

"Took an engine block to have it clearances for a stroker crank they didn't notch the block deep enough for the rod throws so it had to go to another machine shop to correct their mistake. Also they installed the cam bearings wrong and we had to buy new ones and have the other shop reinstall. They also scammed us on the price it went up every time we called or went out there. Very unreliable."

"Great services. Don't sell you things you don't need. Helpful advice. Very precise and reliable when it comes to machining services."
