Inside an SP Built engine: a 416ci LS stroker with Mast Motorsport heads, a Callies Dragonslayer crank and Diamond pistons, built ready for a Harrop 2650 supercharger.
This is the part most people never see. A 416 cubic inch stroker on the stand in our workshop, built with a Callies Dragonslayer crankshaft, Diamond pistons and Mast Motorsport cylinder heads.
Once complete it was ready for a Harrop 2650 supercharger. It is the same care that goes into every SP Built engine.
