Cam suggestions

If the 3.23s are staying, it is IMO, almost a waste of time putting in a different cam, to achieve your goal.
For street;You would be better off with more torque multiplication. Like rear gears or an A999 with a 2.74 low gear.Or a little higher stall.
Your current starter gear with a 727 is 2.45x3.23= 7.91 If you swapped in 3.55s and an A999 your new starter gear would be 2.74x3.55=9.73, which is about 23% more torque-multiplication. 23%! This is sorta like putting on a turbo,( in first gear only). This will also bring your engines torque peak down 23% in the MPH range. Currently, if your engine torque peaks at the factory spec of 3600rpm, this is about 37 mph. With the new set-up, it would torque-peak still at 3600, but now at 30mph, PERFECT for stomping the pedal for a kickdown into first gear,in traffic, and rocketing past Grandma!
First gear will be good to about 51 mph at 6500, second to 91mph and Direct to 140,if you dare.
If you couple this with a TC swap to nothing-too-fancy of 2800,(from factory of about 2200/2400) you will be able to blast off the line as well.
Your hiway revs will climb 9.9% from around 2600 to 2870, at 65mph. And it will suck more gas on the hiway. Perhaps 5% more. Some of this you might get back with tuning.
I would start with the TC. Then probably the A999. And finally the gears.
Now your combo is ready for a cam.
I would go with a solid, on account of it would keep your cylinder pressure up, to protect the low-speed performance, by virtue of the fact that a solid could maintain the ICA to close to factory. For instance, the factory cam is a 268/276/114 cam in at 112, making the ICA = 66*. You can get a Comp mechanical,as an example, that is 274/280/110 in at 106 that would come in at 63* ICA, and so, actually increase cylinder pressure just a tad.This would be a step up. Also as an example, Comp also makes this mechanical; 282/290/110 in at 106. Your ICA with this one is just 1* more than the current cam. This cam would be 2 sizes up.Both cams want headers, to take advantage of the overlap cycle. Both cams may require work to the heads to accept the extra lift.Both cams are fairly tight lash designs, but still make a noticeable racket.Neither of these cams will play nice with your current starter gear , nor the current TC.
Mechanical lifter retro-fits are not cheap; requiring new springs,adjustable rockers and new pushrods, at the same time, plus in some cases headwork to accept the extra lift they offer. I offer these only as examples of what a mechanical lifter cam can do for you.
Decisions,decisions.
I say TC first.
400 to 600 rpm will be a boost in off-the-line performance,whereas a cam may loose it here. And a TC will give a quicker march thru first gear.
