Thanks for the suggested reading buoymaker. I have read the first two, and will give the second two a read.
Joe H, any of the bogging issues at low rpm that Jerry warns about? I'm assuming no by your second sentence.
The impression I've gotten from reading on this site and articles is that two carbs on a stock engine will most likely deter performance, but there are references to some benefit to two carbs on a modified engine, which is why I'm pursuing it. In the end, for me, if I get equivalent performance, or even mildly improved with two carbs, it's a win, so trying to get it right from that perspective.
One thing I've not seen referenced in the threads on two carbs is the dyno tests done in California Bill's book. He claims a 12 HP gain (if I remember the number right) over stock on the dyno, with the only change being the two carbs from stock. The carbs used were Zeniths, which I have not heard of. Is there an argument out there to rebuke the claim the book makes?
