MOTORHEAD The 2 cams I have run and a 4 degree total for all torque. My car is 2705 pounds in weight with 1/2 tank of fuel and no driver. First motor was a 452 with 9.0 compression. power was 448 torque and 368 HP with a hydro lifter cam of 501-533" I did have work done on the heads. Car was very drivable. Down side was smoking tires in first 2 gears. These where BFG tires. I changed the car over time to a 482 motor with 10.5 compression. Power is 620 ft of torque and 530 HP. I went to a 335/35 r17 tire and they just blowup unless I roll on and off the throttle. I am going to advance the timing 2 degress to kill some of the torque. Will loose about 30ft of torque off idle. cams specs are 587"-607" hydro roller. If you just adjust your driving style, you will be fine. The trick is learning to drive all over again with more power. I am happy with running torque motors over HP motors. They make good power and last longer with running in a lower rpm range IMO. It's sad to say, That I can pull trees out with the cobra better than the truck.
