Some thoughts:
1. It's a '66 Hemi block and would look nice sitting in a street car, probably go nice too. I imagine that's why the question.
2. Before you do anything else, Magnaflux or dye penetrant check the block bottom end for cracks.
3. If you have 2" of space at the top it'll probably work on the street if you pay attention.

This , add an oil cooler and you should be ok for the street as long as you aren't idling in a line waiting to get into someplace for an hour .
Question though apollo , have you checked the deck height ?? Many of those drag hemis had the decks cut ... to the tune of .100 or more.
