First pull produced 356 HP @ 5955 RPM, and 328 FT LBS TQ @ 5517 RPM.
Last pull produced 372 HP @ 6156 RPM, and 340 FT LBS @ 5262 RPM.

They went up 3 sizes on the secondary mains, and installed a one size larger pump shooter on the primary to cure a tip in stumble. Cost was $250.00, for three pulls, and that included the parts.
