Best carb choice for 318

Great thing about being in Ohio is Summit parts arrive the day after ordering them. I got the carb on Friday and have it mostly installed. Need to modify or make a throttle cable stud as the hole is smaller on the Demon then on the extension bracket I had. They sell one for 31 bucks extra (124007DEM) but not sure I can justify that. It fired right up but I didn't have time to get it out of the garage so hopefully a test drive will be in order tomorrow or Monday. Ill post a picture or two of the car if I can remember how to do it on a forum
