I'm pretty sure that Dwayne knows his way around a carb but I'll pass on that sage bit of advice in case he misses this thread
1) The way it was written there is an implication that the carb was not rejetted, i.e. "it was swapped out" The castings are virtually the same. I have rebuilt both Edelbrock and Carter AFB carburetors with excellent results.
2) Dyno testing which consists of just WOT pulls should have the fewest problems. Care to point us in the direction of this article? It contradicts what I and others experience including class racers who state the difference between Holleys and AFB's is slight. I'd like to read the details myself rather than from someone else second hand.
