Hamilton's towing and street grind, built for low-RPM torque and turbo spool rather than peak power. Duration is 178 degrees intake and 208 exhaust at .050 inch, with .290 inch and .310 inch lift, working from idle to about 4,000 RPM. The usual reasons to fit one are quicker spool on a large single turbo and a 200-300F drop in EGT while towing.
