COMPACTED GRAPHITE ENGINE BLOCKS
COMPACTED GRAPHITE ENGINE BLOCKS These blocks offer greater strength and stability, but be aware of the machining concerns. by Mike Mavrigian CGI engine blocks offer greater strength and superior stability with no weight penalty. In theory, a CGI block can be produced at near-aluminum-weight while maintaining needed strength. One benefit is that cylinder walls can [...]
PROJECT 632 PART 6:DELIVERANCE (6C)
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. Recommended fuel pressure is 5-7.5 psi. The anodized billet metering blocks feature changeable idle feed restrictors for easier tuning of the idle [...]
CYLINDER BORE DISTORTION (Part 3)
The hot honing unit is plumbed to the block on the honing machine. The intention is to simulate engine operating temperature (at least in terms of coolant temperature) during honing. THERMAL CONSIDERATIONS DURING HONING Another aspect of obtaining a bore that will remain as true as possible during engine operation involves heat. Consider that although [...]
COMPUTER-AIDED BLOCK MACHINING (Part 2)
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 [...]
PROJECT 632, PART 2 (B)
HONING THE CYLINDERS Following a recommendation from our buddies at Sunnen, we visited Gressman at Gressman Powersports in Fremont, Ohio (Gressman has built a number of 632 motors, in addition to countless big-number drag, sprint car and road-race engines). Naturally, the Ohio winter weather forced us to drive in sub-zero temperatures. Even with the block [...]
