Jim, Youve got a great looking car. Just some tidbits I came across when doing my research on Webers.
Keith Kraft said that you need at least 11 or 12 degrees of cam lobe separation when running Webers. Without that separation it will want to stumble, spit or fire back through the carbs. Others have said that sealing the air stacks to the carbs is important because it prevents air leakage that would make a difference in idling or cause stumbling out of the gate. If an air cleaner is used then these leaks would affect it even more. Some have even said that after they got em running they ran great for a while but then became hard to tune etc. A lot of the time its these small leaks that are causing it. The use of an air cleaner may actually help cause the air stacks to leak at the base if they arent sealed good. Path of least resistance etc.
As far as the performance goes , their response is only 2nd to a roots type blower. After using them Kenny Miles wanted them on every car he drove. He knew that coming out of a turn he could gain a fender on anyone.
Good luck with the car.
Michael
