However, more cam would work better. I would use an old school Comp Cam 292H (244/244, 110 LSA, 0.501"), as it is a lot less likely to go flat due to softer ramps Get the cam hardened and use an oil additive (zddplus.com). Plus you don't need a split duration cam with those heads. Should make power a little past 6000 rpm in a 400 cid, 6500 in a 350.

Good luck!
I DO like your thinking lol, i normally go under the same rule, I'm guessing the 292H will work as well as say the XE284H right? I do run the lucas "zink" additive, so far i've had no problems with both cams i've run, the other seemed to be a bit much & was hard to tune as it only got 6 inches vacuum, even advancing it didn't help much, it too was a single pattern, here are the cams i've run, now running the smaller one.

Cam in there now.

The smaller cam is pulling 16 inches vacuum but fizzles out at around 5800

The car is a 78 cutlass, 3200 lb. with me
