Question which carb do I use?

which edelbrock carb. do I use on my 402BB? The 600cfm 1406 with electric choke?or the 750cfm with electric choke? or 750cfm with manual choke and add a electric choke? I'll be adding an RV cam and boring 30 over.

A 750 should be good for your 402bb. A 600 would proably be a bit too small. I would opt for the electric choke carb. The electric choke on the Edelbrock carbs is great....get in the truck when it is cold, turn the key and drive off. I rarley have to warm mine up over 4 or 5 seconds. Manual chokes are OK, but you will have to run a cable into the cab so you can turn the choke on and off....just like a lawn mower. The electric choke version is also jetted a bit leaner than the manual choke carb, for better gas mileage.
