New carb, new distributer?

I'm running a stock computer controlled quadrajet on my 1986 305 LG4, if i change my carburetor to an edelbrock 600cfm manual choke carb, will i have to change my distributer as well?

So the edelbrock 1405 carb is not a computer controlled carb and will not work with my factory distributor? Do they have a computer controlled carb?

No. The only computer controlled carbs are stock ones.

The computer itself is under the dash, above the passenger's feet.

What it takes to run it is all over - distributor, firewall, thermostat housing, carb, etc.

easiest? don't swap carbs, just fix whatevers wrong with that one, probably something minor.



Otherwise, you'd need a run of the mill HEI distributor, that edelbrock carb, and you'd have to tweak a handful of other things on the car to get everything running right.
