350 truck build. Need a little help.

I am building a 79 chevy scottsdale 4wd truck. It has a 350 in it right now. It will NOT be a daily driver truck. I plan on getting lower gear ( prolly 4.10s) and bigger tires and maybe a bit of a lift. It has a 4 speed manual as well.

right now, I have vortec heads, z28 valve springs, professional products dual plane intake, and a 670 holley truck avenger carb.

I really need some help choosing a cam. I'm pretty sure the 79 block use flat top pistons, so the compression is a lot higher with vortecs (64CC) but I'm not sure how high? Anybody know?
lunati recommended me their 60102 cam, and I am awaiting comps recommendation.
it will be a mud bog and mud drag truck I am hoping.i would like to spin it up to 6000rpm or more as well.

is there anything I'm missing?

thanks for the help!

stroke it.

I would love to, but I don't have a lot of money. I got lucky with everything so far and have only paid a out $350 for everything

I am going to pick up a comp XE274H cam and a pete jackson gear drive for this wednesday :D
