440 source engine packages

Last week I dyno'd a stock stroke 440 @9.5:1 with stealth heads, the smallest cam (520hp pkg) listed with 1.6 ratio rockers, 2" a body fenderwells, wy-and stealth 2 plane and a 750 hollwy 4160. It made 520ft lbs from way down low and peaked at 480ish hp around 5300ish rpm. The stroker combo numbers do not appear to be out of line IMO. The PqX rockers scare me lol. Aside from the gravel roller bearings, the shafts were football shaped.
