BBC BB-3 Xtra Cyl Head 363cc R/P Bare

The BBC BB-3 Xtra Cylinder Head 363cc R/P Bare from BRODIX is designed for big-block Chevy engine builders focused on achieving maximum flow efficiency and optimizing combustion chamber performance. This bare aluminum casting serves as a versatile foundation for high-performance builds, whether for street, strip, or competition use.

Engineered with a 363cc intake runner volume, this cylinder head aims to enhance volumetric efficiency across the RPM range. The "Xtra" designation indicates advanced port geometry and combustion chamber design tailored for modern fuel systems. This casting is a blank slate, allowing for customized component selection, as it does not include valves, springs, pushrods, or rocker arms.

The BBC BB-3 Xtra is particularly beneficial for those looking to rebuild engines like the 427, 454, or 502 cubic-inch platforms. Its lightweight design at 38.95 lbs contributes to overall engine performance, while the precise dimensions ensure compatibility with traditional big-block Chevy mounts and accessories.
