Cam for torque question

It's hard to overadvance a hi-compression aluminum headed SBMer, with this size of cam,and,operating under cruise conditions at 2200 to 2600ish. My 360 has not complained with over 60*. I am currently running about 50*/57* at 2800. Which is 80 mph with my gears.At 65 my gears get me 2236rpm, and the timing is about 44*/51*. The plus 7* is from the dash-mounted dial-back timing gizmo.
To be honest tho, the plus 7* makes very little difference. Sometimes it will pull up the mph 1 or 2 miles an hour, or, on the tach 50 or 60 rpm; on the exact same throttle opening. Other times not so much.
I only fiddle with it now, on long trips.
My engine is currently running a 276/286/110 Hughes cam (230/237@050), and runs rock-solid at 205*, with just 14* idle-timing,so overheating is not a concern for me.
And I like a tuff sounding idle, so I run only the 14*. I installed the DB gizmo as a tool for finding out instantaneously what advance the engine wanted under various loads and throttle openings. And also to retard the timing even more from the 14*,to weaken the power-pulses so the car would not be so jumpy, when parading it around the parking lot(stick-car). The cruise benefit was secondary.
On another topic;
IIRC my 230* cam makes a tic over 10" of vacuum at 750rpm. But the vacuum rises rapidly with rpm. I run my PV to open pretty early. What I did was to install a block-off plug in the PV hole and took the car for a drive. Then I rolled into the gas-pedal and figured out at what vacuum the engine wanted more fuel. Then I put the vacuum pump to every single PV I had, and lined them all up from earliest opening to latest. I pulled one out that seemed like a good match, and installed it. My engine wanted PVgas at about 10 inches vacuum. Since it idled at a tic over that, I couldn't put a 10 in there. But I discovered that the numbers stamped on my PVs bore little resemblance to what the valves were actually doing, so I just re-labeled mine from 1 to 8(IIRC), I forget which direction; maybe 10 fastest opening. It took a couple of tries to get one just right. If it opens too late, I could really feel the sag on tip-in, before it started pulling.Too early is hard to tell, so I aimed for too-late and backed up 1. But you will never know too early unless you have several to chose from and you calibrate them yourself.
I bought one of those adjustable PVs but I couldn't get it to work right, and eventually abandoned it.
