like i said, depends on the intended application. what if i did not like the power band of the stock 360? what if i wanted even more low end toque? maybe for a rock crawler or something. then i would continue to use stock type parts with increased cubic inches. if i upgraded the parts and increased cubic inches, powerband would stay closer to that before. there would be more power still closer to oem. on the other hand if i went even more aggressive, the power band could be rose to more high rpm street or mud bog performance.50ply said:ED-3 is right, the larger ports are what you want for a stroker 360.
