Not Ranked
Rick, well if you have both dyno runs that show the numbers, then I stand corrected.
My engine is a 331, carbed with a Holley 650 DP, and had to be jetted up three sizes on the secondary side to cure a lean condition over 4500 RPM. They also replaced the primary pump shooter with one size larger. No other changes were made. It developed 372 @6100 to the rear wheels.
