Other shop quoted:
Eliminator Ultra block 4.600" bore
Scat custom billet crank 3.8" stroke
Oliver billet Big Block 6.800" rods
Custom Ross pistons
Custom Solid Roller camshaft

Here is my thought:
Eliminator billet block 4.39" bore
Scat billet crank 4.14" stroke
Oliver billet Big Block rods 6.800"
Custom JE dish pistons 8.8:1 cut for TFS A460 with 91cc chambers   Give me your opinions. will this make the power reliably?

I figured it was an old original post so, I should look for an older build which would still be viable.
I had to go look it up in past records of a customer; big single turbo in a boat for a 500 Cubic Inch class.
You need to begin with a good strong block ... I used an A460 Ford Motorsport block.
4.530" bore 7.9/1 compression ratio; Diamond custom pistons.
3.875" stroke... made from a 429 truck crank offset ground to having 2.200" journals.
6.800" length Saenz B.B. Chevy rods; other brands are available these days.
A460 heads
40 inches of boost; that is about 19.5 lbs.
Custom Lazer roller camshaft + Lifters.

The rest is immaterial for what was being asked..

Nice Build Randy.  I "Assume" you went with the 18 Bolt Heads, seems that's a major attraction for the Turbo guys when the Blocks were available?

I know Erica Ortiz got away with the 10 Bolts so it can be done to a point.
