Red,
I like the Edelbrock... had it apart many times this year getting the new motor dialed in, and I like the design.
I am however, stepping up 100 cfm, then dyno running for optimum jetting over the winter. this motor absolutely rips, but it's got more. way more. you can tell it needs more carb. it's over 450 hp now, but I think optimal timing, optimal cfm, and optimal jetting will put it close to or at 500 hp. the Edelbrock is a good carb, I recommend it to anyone who understands carbs and can dial them... there are alot of variables with the Edelbrock that other carbs don't have, but if you know how to tune it, it allows alot more ability to tune. jetting, needle progression, variable springs for secondaries... very nice.
