I suppose it can be done, but I don't know how reliable (or streetable) it would be. Is this just theoretical, or do you have a vehicle in mind for this engine? And what would its intended use be?
You'd have to use virtually all aftermarket parts, including the block. A stock block is good to about 500 hp, after that things get a little dicey. Are you talking about an actual displacement of 302 ci, or the basic 302 package but bored and stroked? It would help a bunch to get more cubes in there to start off with. Perhaps a 347 kit would do it.
And why a 302 when you're looking for that kind of power? Why not a 351W stroker? I think you can get up to 427 ci with the 351W.
I'm more partial to the 302 myself, in part because of the smaller physical size and weight and because it's the basic engine configuration that came in my Tiger from the factory (260). It's a PITA to fit a 351W in there, and you don't really want to add any more weight to the front end in those things.
The key to this beast is going to be the heads. It'll need to flow a ton of air through it. There are a bunch of good heads on the market for these engines nowadays, but I'd have to sit down and do a little research to pick out just what I would use. I'm sure some of these guys here could come up with something right off the tops of their heads though.
How about induction? Carb(s) or fuel injection?
There's quite a bit involved with this project, and if it's something you actually want to do the very first thing you'll need is a hefty bank balance, 'cause it ain't gonna be cheap!

I'm still going to have to agree with TigerDan. To make 650 hp with a N/A 302 ci, I can't think of any stock parts I would use. Not if the engine would have to run for more then a few seconds anyhow.
