Tour Golen Engine Service's New 12,000 Square Foot Shop!

Welcome to the new Golen Engine Service shop. This 12,000 square-foot facility is almost double the size of our last location and allows us to keep up with the increased demand for custom built performance engines.



All of our computer balancing is done on this Hynes balancer. This system allows us to spin up the rotating assembly (crank, rods and pistons) and find any subtle harmonic vibration. The computer then tells us exactly where to remove weight from the crank to eliminate the vibrations. All balancing is completed to within 1 gram-inch.





Boring is completed on the Rottler boring bar on the left. After each block is bored, it is then decked on a Sunnen HBS-1300 on the right. This assures that the deck surface is completely flat and ready to seal against the head gasket.

After blocks are bored and decked, they are ready for the finish hone. This is completed on the Sunnen CV-616 on the right. This machine allows us to reach an exact piston-to-cylinder clearance and make sure the diameter of the bore is exact from top-to-bottom. Also, if the block needs to be line decked/honed, it is completed at this point.


	The bridgeport is used for countless tasks. Some of which include converting 2-bolt blocks into 4-bolt blocks, cutting valve-reliefs in pistons and opening throttle-body bores on intake manifolds. With the attached Digital Read-Out, we are able to cut with the accuracy of a CNC machine.

The Serdi is our head workbench. With it, we can install new valve guides, cut performance valve seats, and generally overhaul the head. The floating cutting head on the machine allows us to work on just about any kind of cylinder head.


	The rod station is used for resizing and finishing connecting rods. It includes a cap grinder and a small hone. When new press-fit rod bolts are installed, you have to resize the big-end of the rods as they get distorted. These machines allow us to do this with excellent precision.

Our 1,500 square-foot assembly room is where the magic happens.
This is where final machined components are matched with race-quality parts then painted and polished to create a performance assembly02 engine. Our engine builders measure the tolerances of all bearing clearances and usually build the bottom end two or three times before final assembly.
All engines are subjected to an inspection process where two builders and the floor manager check every step in the build. By doing this, we can be sure that nothing has been overlooked and that you will receive a reliable performance engine.

The 2,000 square-foot parts room is where we store all of the components required to build an engine. We stock enough components to build many of our popular packages and maintain enough inventory to keep production times on most engines under a month.

All engines that are ordered with Dyno service are run on our Land & Sea dyno. This dyno is loaded with extra features and allows us to see just about every running parameter of the engine, including oil pressure, oil temp, water temp, air/fuel ratio, EGT, fuel flow, fuel consumption, air flow dyno02 , torque, and of course horsepower. After running an engine on the dyno, we print out all the operating specifications, including jetting and ignition timing, and include it with the shipped engine.
