The body looks really good.
So you are just wanting to power it now, no fancy stuff? Understood.
BTW - (IMO) You want a 292 block for any serious performance as although the 312 is the same casting, the machining protocols weakened the webbing considerably. Just find a 312 crank and rods and you will have it.
And finding a correctly calibrated PCV valve might be a problem as it will affect your fuel curve while trying to establish correct draw/draft.
ENJOY!
