State of the art machining capabilities operated by expert machinists. These machines are specifically designed for High Performance Engine Blue Print machining operations. Custom machine your components  1 part at a time. OEM'S use the Pan Rail as The machining Datum. This is why deck heights are not at a true 90 or equal end to end.Cylinder  bore locations and even lifter bore distances and locations are not on Blue Print Spec. Reid's Automotive has invested in Rottler F67A CNC Equipment with 4 th axis and probing  processes to correct bore center spacing , deck heights and lifter bore locations. Our fixtures are based from the main line and cam shaft centerline. The process will increase Horse Power while Improving overall Engine Performance. Your Hot Rod, Vintage Restoration, Marine Engine, or Race Engine will perform at peak performance levels.

Reid's Automotive utilizes the best components and machining processes. Reid's Automotive will satisfy even the most demanding requirements because "Quality isn't an option it's a requirement"

Services performed on our Rottler F67A CNC
Step 3. Install Precision Cam line Locator and 
cam bar.
Step 4. Line up tail stock and 45 degree
datum plate.
Step 5. Indicate datum plate. 
Step 6. Input bore location from print.
Note: Save data for block type for use on
future blocks.
Step 7. Load the block and install precision cam and main locators onto the precision  locator. The locator bars are then installed into the precision datum plate. 
The set up fixture enables all machining to reference the Camshaft and Main Line centerline.
Step 8. The CNC program locates the indicator at the true blueprint location.  The operator can accept the blueprint locations or adjust the bore centers for wear or core shift.
