Another mileage build going on. Cam straight up?

Building a true daily driver 73 Mach 1
Original 2v engine with .020 over flat top hypers.
I've installed a 4R70W and 3.50 gears.

I want to switch to a 4v carb and I will be using EGR so I think I'm going to use a Aussie spreadbore intake from Aus Ford Parts.
My Carb is undecided. I have to have a PVC nipple in the back of the carb base and I want to try to use the Holley throttle position sensor that mounts near the choke. I think an original 4300D uses the same mounting points as Holley so it may be used.

I'm using a Melling MTF-2 cam and my RPM at target speed in locked overdrive at 49mph is around 1500

Cam specs 486/512 lift, 281/296, 106/118 lobe center
sae timing BTC 30 ABC 72 BBC 78 ATC 34 .050 timing BTC -4 ABC 28 BBC 45 ATC -11

So my question is should the cam be installed straight up? +4 or something else?
