I have ran several setups on my 347 as well, for a nice daily driver I recommend the E-303 cam, you can get almost the exact same cam from comp for 100 dollars less, and I have had very good luck with comp. If you don't have the roller hardware I once found a spider,dog bones and lifters on e bay for 50 bucks! good price! (they were used but good)
As for carb, I have tried the edelbrock 800cfm carb on my truck and could never get it to run right. I then put a holly 750 double pumper mechanical secondaries carb on it and it ran great right out of the box. I was very impressed with the holly carb.
The intake I ran was a dual plain Edelbrock, it was a good intake. Also put in a 2300 stall torque converter it makes a world of difference and if driven normally you wont even notice you have a high stall in your car.
A few years later I took it apart and put custom made pistons in it and put a holly 174 blower on it with the 7psi boot pulley, Ill tell you that thing moved! Unfortunately not for to long though, I ended up bending the snout on the crank from the force of the blower. I found out later that a forged crank would have been better choice than the hardened cast Eagle crank. But I guess that is just the way it goes sometimes.
