750 Holley or 650 Holley DP carb for 340-4 speed?

Hey Guys,

I have a 72 Demon with a 340 4 spd (a833). J heads, Edelbrock Performer,
cam is unknown, but choppy. Headers with 8 3/4 rear end and 3:55 gears.

The car will be run at the track most of the time, some street use.

A very knowledgeable friend recommemded that I change my current setup (Holley 3310-2 750) to a Holley 4777 650 DP, with mechanical secondaries and manual choke. He mentioned it would be a better choice since I'm runnimg a 4 speed and will be making passes at the track.

I know carbs can be personal, jiust wanted to hear from the members on their ideas before I do this.

Thanks Guys!
