Stock block or Not?

I have a 1964 Nova that i am trying to convert over to a pro street machine, I need to know weather you think i should go with a very hott! 283 or throw in bored over 400 block? Hit me up later thanks

If you don't want to spend tons of money but can still spend quite a bit I would just put a big block in it, go to somthing like a 396 or a 454, or just go for a high horse 427. If you really don't care how much you spend on it just put an all out 572 in it, that should pretty much blow the doors off of anything at a traffic light.
