BRODIX delivers the industry’s most durable replacement for the LS3 style cylinder heads with the introduction of the BR 3 series. The BP BR 3 is a 100% CNC ported head that features a 280 cc intake port that flows over 363 cfm. The BR 3 is the unported version designed for outstanding “out-of-the-box” performance. Both heads utilize a 15° valve angle, a 71 cc combustion chamber, and a 2.165 / 1.590 valve combination, and accept all standard LS3 components. The BR 3 series shares all of the legendary BRODIX features including easily repairable A-356 virgin aluminum alloy and the strongest deck surface in the industry.
