What kind of carb to get for my mopar 383?

i own a '70 charger with a big block 383, rightn ow it has the original 2 barrel carb on it. i want more power. i like the look of the Edelbrock's rather than the Holley's. So, im on summitracing.com and i have a lot of choices.. i was thinking the higher cfm the more power output right? but what else do i need to look out for? some say electric choke, and some say manual choke. sadly, i dont know what a shoke even does. i've had a buddy of mine try and teach me, but i still dont understand. so.. could you explain to me what a choke is/does in stupid man's terms? and the difference between a manual and electric choke? and what is this Single inlet and Dual inlet on the carbs? would i be okay with a Edelbrock Performer 750 cfm, 4 barrel, manual choke, single inlet? my motor is all original and stock right now. i am going to beef up the cam later on, but for now, would this carb be okay? if not, can u lead me in the right direction? and do i need a new throttle cable to the gas pedal?What kind of carb to get for my mopar 383?
a choke opens the carb up to left in fuel and air electric is way to go for street machines manual choke is not harder but you have to choke carb



you dont want to get a big cfm carb but not small see



a big cfm carb will smother you engine in fuel and air



a small cfm will deprice it from fuel and air to get this



take you horsepower and divcide it by the rpms



example



335

over

5200 rpms



that comes out to about .00645 or what ever but take the first 3 digits you see andf that will probally be best carb

Ive got a 383 mag out of my dads 68 charger (lived up north and body died a long time ago) it has a 800 cfm Carter carb., a 750 cfm will work fine, edelbrock, i haven't had any luck with. Looks arent everything, i would go with a holley 750 double pumper, vacuum secondaries if worried about better gas mileage. (its hidden under the air cleaner anyway) Chokes, I'd go manual. The choke cuts some of the air supply into the motor causing a richer air/fuel mixture making it easier to start on colder days(remember the old pump the pedal 2 or 3 times in the winter) that usually set the manual choke, and puts some xtra fuel in via the accelerator pump. Single inlet has one fuel line in, dual=dual hope this helps
