This cam does have slight lope to it at idle in my 400. Im going to try my 670 heads on it thi year. Hoping to get car into the 13s. There not kidding about torque in a 455 either, cause I had this cam in my 455 for a year, in a 83 GP with 6X-4 and and the same intake set up as the 400 and 2.73 gears and it ran 12.97@104mph with lots of wheel spin in second gear.
