LS PROJECT, PART 2 BLOCK PREP AND BALANCING by Mike Mavrigian all photos by author We swapped out the OE torque-plus-angle main cap bolts for a set of ARP studs. This will provide added strength and will eliminate wear on the block’s female threads during future servicing. I recently visited Gressman Powersports where Scott Gressman [...]
A precision mounting plate is installed to the rear of the block. This accurately locates the block to the machine’s base fixture. A centering bar is inserted through the main bores. The main bore centering bar is bushed to accommodate the specific block’s main bore diameter. A camshaft tunnel centering bar helps the machine to [...]
CNC-MACHINING AN ENGINE BLOCK A step-by-step overview of a specific block being machined on a CNC from start to finish. by Mike Mavrigian all photos by author CNC machines vary in terms of footprint size and axis capabilities. Thinking about taking the plunge and buying a CNC (computer numeric control) machine? Or have you wondered [...]
CARBURETOR/FUEL PLUMBING Our big-gulp carb is Holley’s Ultra Dominator (P/N 0-80673), an 1,150 cfm race carb that features billet metering blocks, three-circuit metering, mechanical secondaries and oversized sight windows for easy float adjustment.

HOW DO I USE THE MACHINE? If you opt for a “universal” CNC machine, you’ll need extensive training to learn the computer “coding” language required to create programs. However, if you choose a CNC machine that was designed specifically for use by engine builders, operation and the overall learning curve is much simplified, since programs [...]
