Even though the drive hub system will be clamped to the crank snout with the 6-inch long center bolt to prevent the possibility of independent hub rotation, two roll pins are installed to the hub. The countersunk inside face of the ATI Super Damper was then drilled to accept these roll pins. Plumbing the vacuum [...]
The BG fuel log is adjustable for length, allowing bowl-to-bowl spacing to be set by simply slipping the male tube inside the female tube. The male tube section of the BG fuel log features three sealing O-rings. Fitting the BG fuel rail to our Dominator was a piece of cake. I installed the Race Pumps [...]
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 [...]
The upper intake manifold plenum box gasket is stainless-steel reinforced and provided a perfect fit. The upper plenum box is secured with 1/4″ x 20 x 3/4″ stainless socket head cap screws. I applied a dab of moly to the threads prior to installation. I tightened all screws to 60 in-lbs using a criss-cross pattern. [...]
Using my Goodson 1.8″ – 2.6″ valve spring height gauge, we set final spring installed height at 2.150″. The original valve guides protruded a tad too high for adequate retainer-to-guide-seal clearance. Using a 1/2″ guide cutter and an 11/32″ pilot, I cut the guides down by 0.147″. During intake manifold and gasket test fitting, I [...]
Our chromoly Manton pushrods feature extended lifter tips and hardened rocker tips. Our order consisted of three different lengths. All exhaust pushrods are 1/2” diameter x 11.124”, while intakes were 7/16” tapered in lengths of 10.953” and 10.805”. Here you can clearly see the length differences. From left to right: 11.124” exhaust pushrod, 10.953” intake [...]
WATER PUMP Installing the Meziere Enterprises electric water pump P/N wp300 was a breeze. With gaskets lightly coated with UltraCopper RTV, I snugged the four ARP 3/8″ x 16 x 1.250″ stainless bolts to a specified value of 25 ft-lbs (Meziere supplies socket head cap screws, but I opted for the ARP polished stainless just [...]
CLAMPING OUR HEADS Using ARP moly lube on our stud threads and nuts (and on both sides of each washer), all nuts were tightened to a value of 65 ft-lbs, with the exception of the four special inboard (lifter valley side) studs, which were tightened to 45 ft-lbs. Note: Because the four lower outboard studs [...]
632 Part 5: THE ASSEMBLY CONTINUES by Mike Mavrigian photos by author In this article installment, we deal with a few minor challenges during the final fitting phase, but nothing too daunting. The details are provided here PUSHRODS In order to handle the demands of this engine, I ordered a set of extra-beefy custom pushrods [...]
ANTI-FRICTION AND OIL MANAGEMENT COATINGS Anti-friction coatings (which would be applied to components such as bearings and piston skirts) not only provide a much lower coefficient of friction (when and if physical contact between two moving surfaces takes place), but also serve to retain surface oil between moving parts, which is exactly what you’d want [...]
