Trick Flow® R-Series Carbureted Intake Manifolds for GM LS3

The R-Series intake manifolds by Trick Flow are computer-engineered to deliver carbureted-style aspiration to GM’s LS3 engine. Important features include A319 aluminum construction, a one-piece spider-type design, high-flow individual runners combined with a raised plenum floor, integral bosses for adding nitrous, and extra material for custom porting. These manifolds are intended for heavily modified engines that operate in the 3,500-7,500 plus RPM powerband. For use with Holley 4150-style square bore carburetors; overall height to the mounting pads is 6.285 in.
