Blown big blocks

I've got a somewhat stranded 496ci blower motor on the stand that I've been building over the years.
No real planning was involved, just using the parts I luckily ended up with over time. Street use mainly.
Only the cam has been chosen by Dwayne Porter from PHR.

I think I would worry a bit about the 4000 stall when you have enough torque to reverse spin a small planet at lower rpms.
