For street performance and mild bracket racing. Under 7,000 RPM, under 500 cubic inches. Excellent midrange torque and power, good for heavier vehicles. Inspired by Darts championship winning Pro Stock designs, the PRO1s race proven features include rolled valve angles, improved spark plug location, extra long intake valves, raised exhaust ports, and fast burn chambers yet the PRO1 310cc can be used with off the shelf pistons, valve train components, and intake manifolds. Long wearing Bronze valve guides, screw-in studs, multi-angle intake seats with hardened, radiused exhaust seats are standard. Best of all, our precision cast ports produce outstanding airflow without time consuming porting. Assemblies include Stainless Steel valves, premium springs, locks, retainers, guide plates and seals.
