if you are ready for a set of real heads, and have a few grand kicking around, i have may have some AFR227's i would be willing to part with. lol! that is very decent power, enjoy the ride!

Looks like a wide LSA cam with small heads. If you're going with small heads on a 396 and want it to perform up top it needs more overlap. The wide lsa is making table top torque curve, just not much of it. I'd cam it up more like a 248/256 on a 106, ICL somewhere around 104.
Also not sure how you collapsed a Comp 875 lifter??

Looking at that graph, if you have good valvetrain components I'd run that bitch out all the way to 7000rpm on a dyno to see what the curve does. You aren't losing all that much power at your peak.
According to LPE, 202/80.

It's 40+ year old knowlege - more overlap crutches limited head flow.

Ed Curtis cut this cam with a full spec sheet on hand. I left it in his hands. Hmm...

No reason you should have a SR if you can't at least rev to 7K.
What kind of exhaust/headers are you running?

After looking at it, the curves are fairly close to my graph the way they behave. The difference being my graph is portrait so everything is more dramatic.
Only certain f-body bros are privileged to see such information.
You mean 1 3/4" I'm sure. With the right gears that car will be fun on the street and should do not bad at the track. Not sure where you'd feel comfortable shifting, but I'd shift around 6600rpm and go from there... If you want to optimize the CID then different heads and cam should be used IMO.

I feel comfortable spinning as high as I need to as long as its not a waste
It has 4.30's also

Good reference material if you need to figure out a tire size for the strip:

That curve looks like it'd be a tire shredder on the street.
I agree with some of the others though, another cam with a tight LSA and more overlap and let her ride. That many cubes could also do well with perhaps some AI 215 TFS heads, but you could probably net a good gain for less $ by just swapping the camshaft and keeping the heads you have.
It all depends on your budget and the goals you have. The 396 you have now is not by any means the hottest HR 396 around, but it's not the laziest, either.
