Okay, I have been laboring under mistaken impressions. I thought the carb on the 68 coupe was a 4100, but on closer inspection, it appears to be a 4300. I've read nothing but praises about the 4100, but the 4300 doesn't seem to be held in such high regard. Here's the question. Should I rebuild this 4300, or replace it with an Edelbrock when we put the new Performer intake on during the rebuild of the 302? I'm not looking to really increase the cfm for the boy's daily driver. Thanks.
