Thanks to all who chimed in. I know this is a little late, but I figured I would update those who were interested. I went with a Holley 770 Ultra Street Avenger. The difference in drivability is night and day. Love having a choke. With the heaviest secondary spring in it on a muggy night, it went 11.60s at 115 with about 3/4 throttle. Were there better carb out there? Maybe. But I'm extremely happy with my purchase. Dialed in with light spring and properly tuned, and full throttle, I'm not convinced it will be any slower than it was with the old "race" carb. But because of the carb, I've put more miles on the car in the past month than I have in the past 3 years. Street tires went on a couple of weeks ago, so I'm done racing for a while. Between tires and carb, this car is an absolute dream to drive. Thanks again to everyone who chimed in with advice as this car has evolved into what I have wanted over the past few years!
