RPM Motors is a state-of-the-art custom engine machine shop. We incorporate 40-plus years of experience with the latest technology and a complete inventory of machinery to offer our customers quality high performance engines and engine parts.

We use only the best equipment and processes in all our block machining, rotating assembly and cylinder head preparation. We do head porting on Rottler 5-axis machining centers and flow testing on our Super Flow 600. We use a Heins computerized three-plane balancer to balance our assemblies and DCM equipment to provide proper surface finish of block and cylinder heads. Please see the shop tour on our website to view the rest of our machinery.

Though our main focus is on GM engines, typically the LS series, we also build high performance Ford and Chrysler engines. We offer a full line of automotive and high performance engine parts including our own brand of connecting rods and crankshafts. Additionally, we offer specialty services such as cryogenics, thermal coatings, and powder coating.

We are a full service engine machine shop that goes the extra mile to provide our customers with the best service and highest quality engines.
