 We used COMP Cams’ Ultra Pro...  We used COMP Cams’ Ultra Pro Magnum 1.6 rocker arms on both the intake and exhaust for a total of .688-inch lift at the valve tip. These rockers are made from investment-cast 8650 chromoly and are designed for extremely high strength with minimal weight. They are engineered to be used in high-lift cams without the need to convert to more costly shaft-mount rockers, or even the need for a stud girdle.  This is how good the CNC work...  This is how good the CNC work is on the Dart Pro 1 heads: The 1206 Fel-Pro intake gaskets fit the port openings just about perfectly.  Tony installed a set of Dart...  Tony installed a set of Dart adjustable guideplates on the engine. These interlocking plates allow you to line up the pushrod, rocker arm, and lifter bore, and then lock them in place when the rocker stud is torqued in place.  The Dart single-plane intake...  The Dart single-plane intake manifold is meant for high-rpm, no-nonsense engines like our 427. It fits standard 23-degree cylinder heads and boasts one of the largest intake plenum volumes of a single-four barrel intake for a small-block. We’ll use an HVH 2-inch Super Sucker transitional spacer between the intake and carb during the dyno test to further increase plenum volume and smooth the transition from the carb base to an open intake.  For ignition on the dyno and...  For ignition on the dyno and also in our Laguna, we chose a Performance Distributors HEI. This is an all-new distributor that makes high-performance ignition a breeze. The ignition module, coil, and everything else we need is all in the distributor. We opted for a composite gear for compatibility with our roller camshaft and a set of LiveWires, which have high-temp sleeving and numbered boots for easy installation.  One of the coolest features...  One of the coolest features on the Performance Distributors HEI is the instant timing knob that gives you the ability to adjust the timing without loosening the distributor hold-down. An external knob mounted where you might expect the vacuum advance canister (an unneeded component on this engine) allows you to quickly and easily adjust the timing without any tools.  While we didn’t need a water...  While we didn’t need a water pump on the dyno, we’ll need one when the engine is dropped into the car. We’re using an aluminum Weiand Team G pump for good flow on the street and very lightweight construction.  We got our hands on two of...  We got our hands on two of the brand-new Holley Ultra HP carburetors: one a 850 cfm (left), and the other a 950. The Ultra HP carbs are aluminum for weight savings, have larger fuel bowls, billet aluminum metering blocks, integrated idle bypass valve, and plenty of adjustability down the line to get it dialed-in for the street. We really like the new Hard Core Gray anodized finish.
