The vacuum pump and alternator setup hangs low, leaving the head area clean. Belt tension adjustment on radius tooth setups don’t require much tension at all, which removes a bit of stress from the crank. The tooth engagement alone provides a positive pulley drive. Routing the -12 plumbing from the vacuum pump to the valve [...]
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 [...]

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 [...]
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 [...]
