A Plus camshaft
If you've done your reading, then you know that "Scatter Pattern" cams are designed specifically for the peculiarities of the A-Series engine with it's five-port head. By optimizing lobe centers and phasing for each cylinder, improvements have been made in torque and bottom end power. The result is much better driveability in a very high performance cam. These Kent cams are sold outright, no exchange. The only upgrade in camshaft you can get away with on the single point injection cars without changing ECU etc--A mild road cam. Reprofiled A plus cam sold outright.
