What to do with it?

Use it in a .060 over 318 with the 302 heads and the rest.JMO
That or what buy $350 inserts to run it in a 360? f that, may as well buy a stroker crank if you wanna spend money.

I wouldnt waste much time with a .060 over 318 block. Probably pretty thin and you could easily find a standard bore block for real cheap.

also 3.58 is standard 360 stroke so buy the spacers would be a waste. You can buy a new 360 main 4" stroke crank for less.

I all ways wanted to do a 372 using a 340 block for some reason.. But its really the same thing as a .100 over 360. If you can find a block that would go that far.
