Buy the non-remanned one, it's only $30 more. A 600 will be great for a 306.
100% volumetric efficiency = 567 cfm = 302 CID * 6500 rpms /3456 running at 7000 rpms and 100% VE you would only need 611 CFM. Since your engine is at best going to get 90% VE a 600 is an excellent choice for a 306 going up to 7000 rpms. If you are going to rev past 7000, get the 650. You'll have better driveability with the 600. http://store.summitracing.com/partde...5&autoview=sku

Be careful what you buy when it comes to carbs. You cannot buy one new for much less than $300.
