The HYper pistons are a great choice to cut costs and still have performance. The come with modern rings, flat tops and raised compression height to raise compression. They do not cut any weight from stock and are not to be used in a engine that will see detonation. They are known to break just like a cast piston.
We have a new roller rocker that will fit under a stock Valve cover coming out. This will cut costs and allow cams with .480-.530 lift. This will cut costs as a head will not need to be prepped for screw in studs.
Use our dula exh manifolds, Our SPA intake and have fun driving it.
