Small Block & Big Block Chevy Specific - cam help guru's knowledge please

i have a 1985 K5 gmc jimmy im currently in the process of building a new motor for.
please keep in mind this truck is a 4x4 so i need good torque to get this heavy sob down the road and thru the mud.
heres the rundown of my parts:
l98 1 pc rms hydrolic roller block
stock crank
pm rods stock length
cast pistons ( flat top ) should net me close to 10 to 1
gm vortec 906 heads, mildly ported, stock valves, runners smoothed, bowls cleaned up, exhausted ports too
edelbrock vortec performer ( not rpm ) intake
msd hei dizzy and 6al
taylor wires
ngk plugs
carb, i have a 650 and a 600 edelbrock to work with and really dont want to go past that.
the truck ive converted to a 700r4 with a stock stall
truck is stock geared and im not changing gears
im throwing in long tube headers and re running exhaust, but not done yet will be done after motor swap.

now:
what im looking for is a cam that is very streetable , decent gas milage and will still get me thru the mud on the weekend excursions.
im not looking for a max effort cam here, its not a race car it a truck and i use the 4 wheel drive every so often but more then not its a street truck, to and from work and riding my kid around.
some things ive kicked arround is the zz4 cam or a hotcam, but im totally asking for peoples opinions, suggestions, and life based experiences

thx!

you'll want a cam that has less than 210 deg of duration on intake and exhaust, once you go over that you start moving the torque peak to the higher rpm ranges, which means more hp but that's not what you need.
Overlap is the amount of crank rotation that both the intake and exhaust valves are open on the exhaust stroke. more overlap is good for high rpm power because when the intake valve opens sooner that's more time for the air/fuel charge to enter the cylinder and the open exhaust valve helps pull in the intake charge. but at low rpm when the intake valve opens too soon because of overlap, exhaust gas is directed back up the intake and gives a poor idle along with loss of low rpm performance. So for best low-mid rpm torque you want the greatest amount of cylinder pressure, which is gotten by closing the intake valve shortly after bottom dead center along with having minimum valve overlap. Generally a higher lobe separation angle (LSA) will result is less overlap, but don't take it for granted without looking into the details such as intake/exhaust valve opening/closing points. I think most stock cams that are in trucks are like 190 to 202 degrees of duration.

thx for the reply 1 fmf thats really helpful
as of now im still in wonderland on the cam
i have basically everything else as stated above, or its on order and on the way
heads n block go to the machine shop in 2 weeks so my cam selection time is drawing very near

oh and i thought i should ad compcams camquest 6.0 seems pretty much useless
its top 2 reccomended cams were an ls series cam and a efi cam
go figure

anyone else have some help?
