Build suggestions for 340?

Yeah; ...
Of all these numbers, the only one that the Wallace wants is that 61* Ica
done
So with that new number:
Number of Cylinders : 8
Bore in Inches : 4.08
Stroke in Inches : 3.31
Rod Length in Inches : 6.123
Static Compression Ratio : 10 :1
Inlet Valve Closes ABDC : 61 °
Boost Pressure in PSI : 0
Target Altitude : 800 (Feet)

Static compression ratio of 10:1.
Effective stroke is 2.63 inches.
Your dynamic compression ratio is 8.15:1 .
Your dynamic cranking pressure is 163.28 PSI.
Your effective boost compression ratio, reflecting static c.r., cam timing, altitude, and boost of 0 PSI is 7.99 :1.
V/P (Volume to Pressure Index) is 135
