Joe, I just checked the Holley site to see how that carb works...with no secondary shooter, does the primary pump squirt for the secondaries when they open? Interesting, I thought (until now!) that mechanical secondary carbs all had metering blocks and accel. pumps! Ah, well, ya lives and learns...
But ne'er the less, I have also heard the 450s are a good choice.
