100 cfm more with anular and downleg boosters can't beat AFR

Sure do!
That's one of the times I was trying out the autolites.
Just checked - Nov 2009

I have both threads saved with pictures. Do you still have the cam card with the timing events in particular the intake closing points?

Edit: Never mind I think I found it here:

#8---Older Camshaft Profiles (Big Block Hydraulic: HE Series)

It shows the @ 50 timings but not seat.
