My first engine project BBC/454

I have a lowered 71' Chevy C10/Short bed that is used mainly for Saturday night cruising. I'm in the process of rebuilding the 454. What I have so far:
1989 454 4-bolt Mark IV block with Scat 9000 crank and Eagle SIR I beam 5140 steel connecting rods. Heads are new aluminum Edelbrock Performer RPM oval port Edelbrock Dual-Quad intake with two Carter AFB 625cfm carbs.. A TH400 trans. w/shift kit. A 12 bolt rearend non-posi with 4.11 gears running on Goodyear Eagle 295/50R15(rear) 235/60R15(front). I hope to change to a posi and a little milder gears in the future.

Question (1) I'm have trouble diciding on a cam shaft, the one Edelbrock suggests as part of their " Power Package" has Int 240 Exh 246 at .050, Lift of Int.560 Exh.573, power range listed at 1500 to 6500 RPM. Is this a good "streetable" cam?

Question(2) What kind of pistons should I go with to keep the compression below 10? (I'm thinking a .095 dome)

Question(3) What size of a Torque converter should I use?

Question(4) Whats the pro's and con's of going with the Dual-Quad vs. a single 850cf carb

My concern in all of this, is balancing Hp with Torque on what I think is a 4000 to 4500lbs vehical. I know this is a long posting, but everything works together and I would like to get it right.

the edelbrock cam isnt the best grind out there but it will work, it will have a nice rumble to it..I would suggest the com cams x-treme 274 for your 454, and only because I have ran this cam in a 402, with good results..With the added cubes the torque should be breath taking...

10:1 w/ aluminum heads should be fine on pump gas and thats what I would recomend..

I would use a 2500 stall, any less and the shifts between the gears will be harsh, and it will work well with what you have..In a big block a 2500 stall will likely stall a little higher and thats even better..

Ill only say I had the two 4's set up on a 427 in a 67 impala and I didnt like it, it had 2 old carter carbs but they worked ok, it just didnt run that well, I stuck a performer RPM intake on it with a 800cfm DP holley w/ a 2" spacer and it did run much better, and later I stuck a 402 in there and tried the 2 4's again and had the same results..I couldnt keep the carbs adjusted right and it didnt want to open up on top end like it did with the single holley..

I would forget trying to hook it up untill you find a posi, I would however use the 4.10's and run a 28" tall or taller tire on the rear..
