Should I change my cam?!

Alright so I'm about to redo the engine/trans/rear-end/brakes on my '77 D100. The truck is a single cab long bed and weighs 3800lbs without me in it. It's a 2wd with a 318/727/8.25 in it. It haos served as an on and off daily driver and my only truck for more than 5yrs now. The old original drivetrain had around 185k on it and was just totally worn out.

The goal is to make it a reliable daily driver, that performs like a truck should, and is fun to drive and hotrod around in some.

So the engine build so far consists of the following

'73 318 (measured at an actual 9.1:1scr)
Stock crank and rods
0.030" over factory replacement pistons
MP windage tray
High pressure oil pump
"302" heads (gasket matched, ported, cut 0.030, 1.88/1.60 valves, MP valve springs and retainers)
Eddy LD340 intake (gasket matched, center divider knife edged)
1" phenolic spacer
Street Demon 625cfm carb
MP electronic distributor
MSD Streetfire plug wires
Hedman block hugger headers

Fully rebuilt A727 trans
New 2200rpm torque converter

8.75" rear end with a 3.23 SureGrip

So all this is locked in. These are the parts and specs of what I already have ready to go. I'm not changing anybody the aforementioned parts.

Now here is the question: Should I keep the cam that is in it, or should I get a milder grind?!

(and for all you guys that are gonna bash off the shelf cams and say I'm an idiot for not getting a custom grind, don't waste you're time responding).

It currently has a MP P4452761 cam in it.
