I am by no means a expert, but I did plug the cam numbers into DD200. You may want to look at the summit 2801. At $59 dollars it is hard to beat. In the picture the 067 is first, 068 second and the 2801 last. From what I see on the charts is that the summit cam will move your horsepower higher in the rpm's. Just a thought.

Thanks for the crunching. Looks like the 067 is really great if you want lots of low end torque and power fast!
I do like the torque curve of the 2801. Thats one that I have come to several times. That is certainly a good option providing the intake valve closes after that of the 067 thereby offering less dynamic compression in the highway driving rpm range. Given the sad state of oil/flat lobes, a cheap cam is value in itself!

Been down this road with 400's and these cams in the past. The 067 is great in the 350 Pontiac, but too mild in the 400, as you have discovered. The 068 is fine (still mild but not as mild as 067) and your brakes will have no problem either.
I like the Nunzi 2041 cam much more than the 068. It is a better version of the 068 but with higher lift and tighter 110 lc. If you tune it right, your brakes will be fine with this one as well. I never liked the 744 personally. BTW, Nunzi once told me the 067 in a 400 is like putting a "broomstick" in there! That man has such a way with words!

The crower 60916 could also work, although your rear gear is a little low (numerically) for it. If you had a lose converter you'd be ok. Plenty of vacuum for power brakes.

I have always liked the 744 cam but with a 2:93 gear it would be a pig out of the gate.I use it with a 3:42 gear [400 6x "4"] and adv the cam 4 degrees [1.65 rockers on the exhaust/1.5 on the intake] and a 2600 stall and it ran very well.Driving it 110 miles[1 way] to the track it ran an 8:68 @ 82 MPH on P275-60 radial tires with a WAY to small elderbrock 600 cfm carb.
