I have one that was a racer brown and sold under the old Mopar DC line Great cam from 4000 up but horrible fuel use and stink ass idle. Use a Holley to clean it up Loved the power up top got tired of lack of torque down low even with 4.10s. Finally changed out after years of use and went with a way better cam for me a hotted up version of 68 340stick cam. Plenty of power and still revs. Now can pull out in 3rd gear
