PROJECT LS2, PART 5 INDUCTION AND IGNITION by Mike Mavrigian all photos by author Our LS2, ready for induction. You face a few choices with regard to fuel, air and ignition when building an LS-you can stick with the OE fuel injection (how boring is that?), you can install an aftermarket performance fuel injection system [...]

The Victor water pump mounting gaskets are alloy bases with elastomeric seals. These appear to be very re-useable. Our Edelbrock water pump mounted to the block. Fit and hole alignment were superb. Here’s the upper left timing cover bolt that we mentioned. It’s close, but it does clear the pump body. The Edelbrock water pump [...]

ROCKER COVERS AND COIL BRACKETS Instead of using a pair of boring OE rocker covers, we opted for a pair of Moroso welded aluminum cuties. These beautifully tig-welded covers accept the OE type formed gasket seal (each cover features a CNCed groove on the mating surface). Each cover is secured to the head using OE-type [...]

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 [...]

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 [...]

Our initial distributor offered a very neat low profile, but the large diameter of the head made installation impossible due to a lack of intake plenum clearance, so I switched out to a smaller-diameter-head MSD. The MSD Pro-Billet distributor (P/N 85501) provided the intake manifold plenum clearance that we needed. Our MSD distributor features a [...]

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 [...]

VALVE COVERS The 1/4-inch x 20 x 3.5-inch socket head cap screws supplied with the Moroso valve covers are fine, and function perfectly. But, being the anal dolt that I am, I wanted to dress things up a bit more. I installed stainless-steel 1/4-inch x 20 x 4-inch studs into the heads (purchased from McMaster-Carr [...]
