318/410 What do you think (posting for a friend not my engine)

I bored out earlier 318 blocks to 4.040 with stock stroke, but I dont think I would do this with a that much thrust angle leaning on it w/4" stroke.

I'd have done .060 or maybe 4"..then it's only .020 more to 4.040 , it's a circle..so .020 aside =.040 larger ID...so I think I'd stay @.060...=3.97 close enough.
