Keeping the oil in place is a six-quart Moroso oil pan. Inside are several notable features, including the kicked-out sump and crank scraper, the unidirectional windage screen, and a trapdoor baffling for better oil control. We also ordered the matching dipstick and oil stud kit.

To seal the heads into place, we used a fresh set of 0.053-inch-thick Fel-Pro multilayer steel gaskets.

Conventional 24-degree cylinder heads have come a long way and Brodix’s CNC BB-3 Xtra oval-port 332s can flow a copious amount of air. At 0.700-inch lift, these jewels already flow 416 cfm on the intake and 290 cfm on the exhaust side, making it ideal for big-inch and power adder combinations. For springs, ours were outfitted with 1.625-inch roller springs with pressures at 260 pounds closed and 790 pounds open. Brodix also offers optional 1.645-inch roller springs with increased pressures at 315 pounds closed and 915 pounds open.

It isn’t uncommon to have big boosted applications push the cylinder heads off the block. To counter this, we secured the heads in place with a set of ARP head studs over their head bolt counterpart and torqued them to 70 ft-lb with moly-lube.

Up top we used a set of COMP 7/16-diameter 1.7:1 ratio Ultra Pro Magnum roller rockers. We’ve used these on many builds with great success and like the unique web-style design, which helps to increase strength and rigidity. We also installed COMP Cams’ Dual Taper 3/8- to 7/16-inch pushrods with 0.125 wall, measuring in at 9.400 and 8.650 inches.

We’ve been looking for a reason to get our hands on COMP’s latest DuPont Black-Wrinkle powdercoat-finished valve covers. For a pair of Benjamins, these beauties come complete with two chrome breathers and welded baffles, and are tall enough to house aftermarket valvetrains.

To seal the lifter valley, we installed a Brodix HV 2000 manifold. We originally selected the BM 2017-O version that requires a 4500-series carburetor; however, we decided to stick with a 4150-series to show that a properly built 750-cfm carburetor could easily support upper horsepower levels. The Moroso spacer shown here is a modified unit that allowed us to monitor fuel temperature readings. The black hose exiting the manifold ties into the bypass valve, which releases the high volume of air when you let go of the loud pedal.

Blow-through carbureted superchargers are more popular than ever and this is what you need to get the job done right the first time. Thanks to The Carb Shop, we’ve used this particular carburetor on everything from mild 500 hp to well over 1,100hp combinations. We’ve shown complete builds in the past, and you can access that story for full details on our site at chevyhiperformance.com.

Vortech Engineering’s Ysi supercharger can pack a punch and has powered a number of class cars well into 8-second quarter-mile times. Max impeller speed is rated at 65,000 rpm with a max flow rating of 1,600 cfm. For our cog pulley combination, we used an 80-tooth lower with a 29-tooth upper, which produced 16.7 psi of boost. CHP
