I also thought and have read that less is more when it comes to Carb cfm and tunnel rams, but I may be mistaken. There are so many different opinions on carb choice especially when it comes to tunnel rams. And when on a budget there are even more. bought the 450's off eBay and they will probably need a rebuild. Bought the 600's at the swap meet as a pare, and they will defiantly need a rebuild. But I buy what I can afford and try to do most of the work myself, so I don't break the budget.
