My Stock Block 70 360 Build was sonic checked,1/2 filled before machining with torque plates on and filled one side at a time allowing time to cure, turned the block to allow level filling. my builder/ machinist also installed pro-gram steel 2 bolt caps, he didn't like the lack of material in the area where the outer cap bolts would be drilled, and said girdles are a band aid.
Its a 59 deg W9 build, only bored .030" over with 4.125" stroke.

After all the work done to this block I should have bought an 48 Deg R3.
