I agree 100%, and not just because the Carb Guru says so.
Like others including Sammy (in another thread) have said, I had no good experiences with the Holley spreadbore, and I'm a HUGE fan of Holley carbs.
As far as the 3310 that Eric recommends, I ran one on a 292 CI SBC with a GM aluminum hi-rise and the old .030-.030 cam and loved the way it performed. The 3310 is an extremely versatile piece. Just jet it correctly and you'll be happy.
