Axial Racing .28 Spec 2S big block engine

New from Axial Racing is this .28 Spec 2S, a 4.6cc big block engine. Replacing the original spec 1S, the spec 2S features a larger machined billet aluminium heat-sink head for increased surface area and cooling, adjusted timing for increased RPM, 37,500 vs. 36,000, and a three needle slide carburetor that includes 8.0. 8.5, & 9.0mm venturis. All this on top of the standard features which include dual bushing aluminium connecting rod and true ABC chrome sleeve construction for durability. This is a direct bolt-in replacement engine for any .21+ engine mount, and will accept most aftermarket shaft drive starting systems.
