So far, the engine is shaping up like this:
1984 C10 Stepside. Weight approx 4000lbs. (alum heads and intake will help)
Vacuum power brakes.
350 2 bolt bored .030 over.
10:1 pistons
mechanical fuel pump.
Aluminum heads 2.02 intake 1.6 exhaust
64cc chambers 185cc runners
7/16 screw in studs w/guide plates.
Rockers not chosen yet, but probably 1.5 w/roller tips.
Headman long 1 5/8" tube headers into dual 2 1/4" exhaust Walker turbo mufflers.
Dual plane intake, not chosen yet.
600 Holley for now, but changeable.
Muncie M20, 2.52 first gear.
3.73 posi diff.
29" rear tires
880 block,set up for roller cam, so that is how I want to go.
I would like some nice power, but not too radical.
Noticeable idle desired, and power range idle to 1500 on the low end to maybe 5500 or 6grand.

What should I be looking for in a cam?? (needs fuel pump lobe)
U have been considering the LT4 hot cam, p/n 24502586
I have read that that particular cam is intended for lower compression setups.
I have also read some people are not impressed with that cam.

This is intended to be my normal driver, so I don't want to get too carried away.
No towing or hauling, I just want to enjoy driving it.
But, I don't drive the truck as much as I used to............

The LT4 hot cam was designed for, well, the LT4 of all things... lol. From what I remember, the LT4 was right around 10:1 compression which is right where you are at. It's a factory engineered cam that was very popular for quite a while. I'm no expert at all, but it seems like a good match for your combo. You can buy it as a kit with proper valve springs and all.

I opted for the LT4 Hot Cam and purchased one reground from Willhoite's in Oklahoma City.
He ground it with a built in 2° advance and instructed me to install with timing marks aligned per factory.
I will still degree the cam when installing so I know what I have.

We'll see how it goes.....
