What a difference a new carb made on my near-stock Ford 302. Had a Summit 600 CFM which is Holley inside a one piece body. It was just too much for the engine. Never could get the idle down even when throttle plates were closed...still sucking too much mixture through the transfer slots. Plus, the geometry was not quite right for my AOD shift characteristics. Replaced it with a 500 CFM Edelbrock. Worked great right out of the box. Only had to adjust choke and idle speed. Plus, works perfect with the AOD. It was like driving a different car. So the moral here is size your carb for the engine. Bigger is not always better. I'm not knocking the Summit carb. It would be perfect for a bigger engine; was just too big for mine.
