Did ya male a change or two to the idler arrangement? Looks much more solid and definitely addresses my other concerns. Maybe I'll just swap to the 11 bolt pump setup now as the manifold is off.

Yes,
Drilled the idler bolt holes to 3/8" and mounted the idler on the 3/8" water pump using bolt. Using a 5 1/2"
bolt and the 1" and 5/8" spacers.
It is more solid than using the smaller 5/16". With the belt under tension the deflection can be seen.
I would recommend swapping the timing cover to the 11 bolt especially I see you are running a 455 with 6x-8 heads.
Use a late 11 bolt cover with out the timing tab.
