Looking for a carb recommendation

If the carb is worn out and you are going to replace it anyway then I would go with a 950 Holley dp for max power potential....but for what you do with the car, your current carb would be fine.

FWIW, my car has a small street roller (.576/.582 lift) and a Holley 650dp that I transformed to a 750dp with a Proform main body and its not hurting for power (see times below). Those Proform main bodies flow REALLY well compared to the stock piece with the choke horn.

Power depends greatly on the parts combination, and tuning skills. JMO.
