Holley 600 Had Rebuild kit put in to it and I only ran it 3 times since. Rebuild kit was 67.55 from summit Number on the side of the carb are:R84020-3 & 0357 See photos of Carb & Kit that was installed. Carb has Manual choke. I felt the carb was a bit too much for my 302 and went with a Edelbrock 500. Price plus shipping from 16143
