Thanks, The BT series blow through carbs will not run on a NA motor. They have a lot more circuitry in them and move more fuel due to the needs of the bonnet vs the enclosure. The GC series carbs will run both NA and boosted however if plans are to use the enclosure. Hope this helps.a 650 cfm would be plenty. i have really enjoied my wiend stealth intake. Just a thought a blow through supercharger/turbo carb are close to the same price as regular carb's. Just a thought if you ever want to go that way down the road. Look into it. I don't know if there are any issues running those carbs on N/A engines. Barry grant makes a nice one.
On the 306 we would use the 575 cfm carb. If you duration is under .240@50 you can use the Speed series and if it is over .240 the Mighty series. If plans are to add a supercharger or turbo later then go ahead and get the Mighty series up front to save some money.i have built a 306 with kieth black s281 pistons,trick flow heads,ecam,i really cant decided on which one to get thanx to all
