honestly i wouldnt get neither holley or demon. for a street car with a small block i'd go edelbrock/carter afb or a tuned quadrajet. ive run plenty of edelbrock/carter afb's and they are great for the street car. they seem to be of a set it and forget and a holley always requires more tuning than a edelbrock/carter carb. and i would stick with a 670 or 625 edelbrock
I would suggest a good custom tuned spreadbore carburetor, whether its a Rochester Quadrajet or a replacement HOLLEY or Edelbrock unit. The spreadbore is the best design for a street car 8) Nice small primaries, for optimum fuel economy. Then enormous secondaries, for when you lay into the throttle and demand big performance 
really.... q-jet... man the one i had on my 307 was from 81cutlass and sucked always had problems.... choke never worked right.. seemed like it would never stayed tuned trying to get something good to were i dont have to try and tune it to run like it should... ii didnt grown up with these carbs so i'm not an expert on tuning these things out.. , the motor just rebuilt to stock, 68 block, #8 heads i bought the motor 2 years ago, and never heard it run so i'm hoping all is good,but is there a difference from early 70's quadrajet
If you can find one that actually came from a 350 the jetting should be right on. A BOP version might be tougher to find than a Chevy but the only real difference is the angle of the fuel line inlet. You should be able to find a good core and buy a kit for less than $100. I'd probably look for one with a 70XXXXX over a 170XXXXX number.
