FastFieros is proud to have purchased a CNC Mill and lathe just recently to bring the LS1/LS6 and even the new LS2 installs to Fieros and any W chassis car.

With this new equipment comes learning new software to make the most use of this process with the best repeatability and close tolerances. Here is the motorplate just designed with MasterCam version 9 to have exact drill and cut processes each time one of these is made.

The yellow circle holes are the Metric 6 bolt pattern of the 4T65eHD transmission, and the bluegreen holes with red crosshairs are LS1 pattern holes. Then the red circles with red crosshairs are dowel pin holes.
