Using a fuel-injection kit from Street and Performance, the Brodix 540 made 630 hp and 630 lb-ft. It is destined for a show car, so that explains why everything is polished. Using a fuel-injection kit from Street and Performance, the Brodix 540 made 630 hp and 630 You want bragging rights that a new set of big-port, big-block heads can provide. You want the performance boost those large runners and exhaust ports deliver as well. What you don't want is the added expense of new headers, intake, and pistons to get there. Brodix understands your pain. When you finally upgrade your 396 for that 540, Brodix recommends its Big-Block 2 Plus (BB-2 Plus) rectangular-port cylinder head with a 312cc intake port that flows more than 340 cfm. The huge numbers are the result of a CNC porting program that replicates the efforts of hours of hand-porting and flow bench work. These heads flow monster air with the help of an exhaust port that is raised 0.600 inch. The relocation of the port forces you to buy a new intake manifold and new headers or have a custom set made, depending on the car you drive. The heads also lack two extra accessory boltholes on the exhaust flange and the intake face if you want to mount your power steering or A/C. If you want to run the big-block in a street car, the solution is the Race Rite series of heads, which offers the intake enhancements of the 2 Plus series of heads with the exhaust port and accessory holes in stock big-block locations. The first head created for the series is the RR BB-R. Decoded, that means Race Rite, big-block, rectangle port. That is the cylinder head used here. There is an oval-port version called the RR-BB-O, and by the time this issue goes to print, there will be an RR BB-2 Plus. These three sets of heads share the intake port of their Pro Street and drag race cousins, giving them great power potential. They also allow you to bolt them into your big-block car with the minimum of hassles. The Brodix aluminum block is a direct replacement for cast-iron blocks with benefits. The 9.800-inch deck can handle a 4.375 stroke, and the sleeved bores can be punched to 4.625. That's as much as 588 inches. Using the raised cam block, you can add a 4.750-inch stroke for 638 inches. The Brodix aluminum block is a direct replacement for cast-iron blocks with benefits. The The 9.800 block has a standard cam location and is ready for the big roller. In this case, the guys at Brodix used a cam that would produce enough vacuum to operate the fuel-injection system. The cam is a hydraulic roller with 248/252 duration at 0.050 and 0.650 lift on a 114 LSA-not too big even by small-block standards, but the smooth idle and torque production make up for the slight loss in horsepower at the top of the rpm range. The 9.800 block has a standard cam location and is ready for the big roller. In this case, To create a 540, you'll need a 4.500 bore and a 4.250 stroke. The Eagle rotator uses a 6.385-inch H-beam connecting rod and a forged steel crank with a 2.200-inch rod and 2.749-inch main journals. The Mahle pistons are made from forged aluminum with a 10cc dome, a 1.270 compression height, and 1.5/3.0mm rings. To create a 540, you'll need a 4.500 bore and a 4.250 stroke.

The top end of the Brodix block has an extra lug for head bolts in the deck area, and the The RR BB-R heads have a 294cc intake port that flows 342 cfm at 0.700 valve lift or more if you ask for Brodix's CNC porting.

If you want to make more power, the Race Rite 312cc rectangle-port 2 Plus head is on the way. We'd try it with a little more cam and a lot more throttle pedal.
