Stepson and I are nearing the end of this Project. 71 Charger was 318, drum brakes. Now has improved aftermarket Front End, Brembo Disc brakes all the way around, with a new Flowmaster Exhaust, and The 440 in question( came out of a 74 truck)carb that was on it is junk. Which Edelbrock should I go with want electric choke, 750 Cfm. Not trying to run at the strip or anything like that just a toy for fun. Thanks for input.
